Abstract- Dissemination of the result achieved
The project introduces the co-production of green hydrogen and decarbonized chemicals through the electrochemical reforming of green feedstock and waste biomass recovery. Electrochemical reforming involves the oxidation of alcohols or sugar molecules at the anode of an electrolysis cell with H2 evolution at the cathode electrode. No oxygen is evolved reducing the risk of explosion from mixing with H2. Moreover, electrochemical reforming offers the possibility to produce H2 at high pressure, virtually eliminating energy-costly multistage compression. The product(s) of the alcohol oxidation are valuable industrially relevant mono or multi-carboxylate compounds (e.g. lactate and acrylate). The project will achieve its goal by developing and synthesizing molecular catalysts that have multiple advantages compared to metal-based nanoparticles: (1) Every single metal atom of the molecular complex is involved in the reaction, which may considerably reduce metal loading; (2) the rational design and optimization of molecular catalysts offer better selectivity and reactivity control, avoiding poisoning species. Molecular catalysts will be based upon transition metals with appropriate organic ligands that form organometallic complexes through metal ligand bonding. The molecular catalysts developed will be supported on conducting electrodes. In addition, a fundamental understanding of electrocatalytic pathways will be obtained through theoretical kinetic/thermodynamic studies with an integrated theoretical-experimental approach. Such studies will also help in designing the composition of the molecular complexes. Finally, optimized molecular catalyst electrodes will be fabricated and tested in complete electrolyzer supplied with biomass derived alcohols.
