We are glad to announce that our paper on “Biochar based cathode enriched with hydroxyapatite and Cu nanoparticles boosting electromethanogenesis” has been published in the journal of Sustainable Energy Technologies and Assessments and is now accessible online.

Electromethanogenesis is an innovative technology addressing the need of storing renewable energy from unprogrammable sources. It allows for the electrochemical production of methane from CO2-rich wastes on microbial cathodes, in a logic of power-to-gas (BEP2G). The challenge of cost-effective and sustainable biocathodes enhancing the microorganism performance and yield of electromethanogenesis is approached in this work. For the first time, porous carbonaceous cathodes were functionalized with Cu nanoparticles and hydroxyapatite (HAP) and successfully experimented for supporting microbial CO2 reduction reaction (CO2RR) to methane. High methane production on cathodes made of Cu 20%, HAP 10%, and carbon balance (20Cu/10HAP) was achieved, with a maximum of 866 ± 199 mmol m−2 d−1 (projected cathode area, Coulombic efficiency of 64%), corresponding to values comparable to the maximum in literature, but in shorter timespans (8 vs. 30 days). The documented effect of pH stabilization in the cathodic chamber by HAP was one of the main parameters that concurred to the selectivity of CO2RR towards methane.

16/02/2023 NEW PAPER

In this work, in collaboration with Sara Morandi and Maela Manzoli from Università degli Studi di Torino, copper- or iron-loaded hydroxyapatites were studied as active catalysts in the direct N2O decomposition reaction. The obtained results demonstrated the key role of HAP in governing surface Cu(II) and Fe(III) structuring. Copper catalysts showed superior performances than iron counterparts. The structural evolution of the metal species with loading plays a critical role in the catalytic behavior. In the case of Fe-catalysts, a gradual Fe-coverage of HAP surface resulted in an increasing trend in the activity. Conversely, for Cu-catalysts high activity and selectivity were associated with a moderate structuration of Cu(II) in the form of nanoparticles with size of around 1.6 nm.

16/01/2023 NEW PAPER

A new application for hydroxyapatite: sensing heavy metal cations. In this recent publication in collaboratiom with Prof. Trasatti’s Group the great performance of nanostructured hydroxyapatite (HAP) in adsorbing heavy metal cations with the good electrical conductivity of high-surface carbon materials is combined for the crafting of high-content hydroxyapatite electrodes (Hap 84–96 wt.%) endowed with the synergistic capability of detection and adsorption of heavy metal cations (Pb2+ and Cu2+) by water solutions.

27/10/2022 NEW PAPER

We had a dream: we would synergistically join the key concepts of environmental protection and circular economy.

Now our paper “Multifunctional interfaces for multiple uses: tin(II)-hydroxyapatite for reductive adsorption of Cr(VI) and its upcycling into catalyst for air protection reactions” has been published on Journal of Colloid and Interface Science (https://authors.elsevier.com/sd/article/S0021-9797(22)01883-5).

The title leaves no room for doubt: our dream became reality!!

In this study we optimized the Cr(VI) removal capacity of tin(II)-modified hydroxyapatite (Sn/HAP), an interesting material recently studied by our research group in the reductive adsorption of Cr(VI). In this study particular attention has been devoted to optimizing not only the Cr(VI) removal performance but also the entire adsorbent value chain, from the synthesis to the after-life of the used sorbents.
Hydroxyapatite, a stable and low-cost biomaterial, was synthesized by cheap precursors and then functionalized by tin(II) deposition from aqueous solutions. The obtained materials were characterized by higher surface area which assured an enhanced tin(II) phase dispersion. This allowed to double the Cr(VI) removal capacity compared to Sn/HAP materials previously presented in the literature. In addition, the used Sn+Cr/HAP materials have been recovered and re-used in a second step as catalysts in reactions of environmental protection (e.g. denitrification of gaseous emissions, de-NOx, and oxidation of organic compounds).
These promising results could open the way to a “circular economy” perspective in the environmental remediation field.

The success of this work is uniquely the result of the talent and enthusiasm of all our co-workers (Mirko, Gina, Claudio and Laura) whom we have to thank for this.

18/10/2022 NEW PAPERS

Niobium-based catalysts are well-established solid acid catalysts, which in the last decades have received great attention. Since 1990’s, Prof. Carniti and Prof. Gervasini have studied the unique surface properties of niobium oxide and niobium phosphate and its relation with their promising activity in hydrolysis and dehydration reactions for polysaccharidic biomass valorization.

The ever present interest of our group towards Nb-based catalysts is recently culminated in two research papers in collaboration with important national and international groups.

In the first paper, titled “Surface acid properties of Nb2O5–P2O5–SiO2 gel-derived catalysts” and published in Microporous and Mesoporous Materials  (Microporous and Mesoporous Materials, 2022, 343, 112190), acidic ternary solids were prepared by an innovative green synthetic route, developed by Prof. Aronne‘s research team (Università degli Studi di Napoli Federico II) and successfully tested as catalysts in ethanol conversion, with production of ethylene and acetaldehyde thanks to the colaboration with Prof. Guido Busca group (Università degli Studi di Genova). The main surface properties (morphology and acidity) were characterized at both gas/solid and water/solid interfaces in our laboratories.

The second paper is titled “Two-dimensional MXenes as catalytic “flying carpets” to transport biomass valorization towards new horizons: The case of furfural catalytic transfer hydrogenation over noble-metal free niobium-based carbides” and it has been published in Catalysis Today.

It is a cutting-edge contribution dealing with the synthesis and characterization of two-dimensional niobium carbides and their catalytic applications for the liquid-phase catalytic transfer hydrogenation (CTH) of furfural in the presence of 2-propanol as hydrogen donor. This research presents novel results in the direction of using noble metal free catalysts for an important topic such as the furfural valorisation and it is the fruit of a prestigious collaboration of our group with the research group of Prof. Michael Naguib (Tulane University, USA), top-leader in the synthesis of bidimensional metal carbides (MXenes) and the research team of Prof. Alberto Villa (Università degli Studi di Milano), expert in the design of noble metal and metal-free catalysts for biomass valorisation.

Phosphate Enrichment of Niobium-Based Catalytic Surfaces in Relation to Reactions of Carbohydrate Biomass Conversion: The Case Studies of Inulin Hydrolysis and Fructose Dehydration

Mariana Catrinck has been a visiting Ph.D. Student from Brazil. During her six-month stage in our group Mariana worked hardly and collected a huge number of results, but Mariana is also a pleasant person and it was so good to share a part of our lives with her. Although the presence of Mariana in our lives remains crystallized over time in our memories, now also her scientific contribution to the activities of our group has been sealed by the publication of an interesting paper within the Commemorative Issue in Honor of Professor Gerhard Ertl on the Occasion of His 85th Birthday in Catalysts. In this work, some physical mixtures of Nb2O5·nH2O and NbOPO4 were prepared to study the role of phosphate groups in the total acidity of samples and in two reactions involving carbohydrate biomass: hydrolysis of polyfructane and dehydration of fructose/glucose to 5-hydroxymethylfurfural (HMF). The acid and catalytic properties of the mixtures were dominated by the phosphate group enrichment. Lewis and Brønsted acid sites were detected by FT-IR experiments with pyridine adsorption/desorption under dry and wet conditions. Lewis acidity decreased with NbP in the composition, while total acidity of the samples, measured by titrations with phenylethylamine in cyclohexane (~3.5 μeq m−2) and water (~2.7 μeq m−2), maintained almost the same values. Inulin conversion took advantage of the presence of surfaces rich in Brønsted sites, and NbOPO4 showed the best hydrolysis activity with glucose/fructose formation. The catalyst with a more phosphated surface showed less deactivation during the dehydration of fructose/glucose into HMF.

Vincere la materia è comprenderla, e comprendere la materia è necessario per comprendere l’universo e noi stessi”- Primo Levi, “Sistema Periodico”.

Oggi alcuni di noi interverranno in prima persona nell’evento organizzato dalla Centrale dell’Acqua di Milano (https://www.centraleacquamilano.it/eventi/primo-levi-e-la-poesia-della-chimica-a-caccia-di-metalli-pesanti-nelle-acque-e-di-sostanze-nocive-nellaria/) dedicato alle scuole medie inferiori e superiori interessate in un viaggio alla scoperta degli elementi chimici.

In particolare, il nostro talk, dal titolo “A caccia di metalli pesanti nelle acque e di sostanze nocive nell’aria“, vi porterà alla scoperta di un materiale in grado di ripulire l’acqua da metalli pesanti ed inquinanti e, nello stesso tempo in una logica di economia circolare, capace di essere anche un catalizzatore in processi di eliminazione di sostanze nocive nell’aria. Stiamo parlando dell’idrossiapatite (HAP), uno dei componenti principali anche dello scheletro umano. Le caratteristiche di questo minerale permettono di utilizzarlo nella rimozione di metalli inquinanti presenti nelle acque. In particolare, metalli pericolosi per la salute umana come il cromo esavalente o il piombo.

L’evento verrà trasmesso in diretta dalle ore 11.30 sul canale Youtube (https://www.youtube.com/channel/UC__BsutjyiC6Q-izZ8NpG8Q), sulla pagina Facebook (https://www.facebook.com/CentraleAcquaMilano/) e su Instagram (https://www.instagram.com/centraleacquamilano/). Seguiteci!!

ECAPA2018 – Winter Meeting

Dozens of Italian cities are in the air pollution danger zone, with 25 exceeding the EU’s standards for air quality, according to a report by Legambiente, the environmental organisation. In addition, three italian big cities (Turin, Milan and Naples) hold the european record for the highest annual average concentration of PM10. (http://www.rainews.it/dl/rainews/articoli/allarme-smog-torino-milano-e-napoli-le-peggiori-in-ue-4a390a04-aa27-4738-bc94-073ee8d5eb69.html)

Consequently, all the (italian) scientists should be involved in proposing suitable solutions for a cleaner and safer environment.

In some small way, the group of Prof. Gervasini and in particular the Environmental Catalysis for Air Pollution Abatement (ECAPA) Subdivision is making a great effort to develop innovative heterogeneous catalysts for improving air quality.

In this context, Ms. Melissa Greta Galloni (Master Student in Industrial Chemistry) will present our results on “Advanced materials for denitrification of contaminated gaseous emissions”.
