Abstract Herein we show that Pt(111) and Pt(100) can produce the ketone through oxidation of secondary carbon polyols. After Bi modification, selectivity for formation increases. On other hand, observe pure Bi‐modified Pt(110) only produced C3 molecules oxidized in primary carbon, it is facet shows an enhancement activity due to modification. In line with these findings, small Pt nanoparticles are not selective formation. Finally, based on data obtained DFT calculations, suggest positively...
The electro-oxidation of alcohols and polyols plays a pivotal role in energy conversion biomass utilization, offering profound implications for producing via fuel cells the synthesis value-added chemicals, including derivatives green hydrogen, through electrolyzers. Addressing challenge catalyst poisoning need enhanced catalytic activity, this study delves into utilizing p-block elements (Bi, Pb, Tl, Se, Ge, Sb, Sn, In, S) adsorbed on platinum electrodes. This approach is chosen to mitigate...
Many polyols are abundant and cheap molecules highly spread in the biomass. These have an enormous potential to be used electrochemical devices generate energy and/or value-added molecules. The electrooxidation of can produce different substances interest chemical industry concomitantly high purity hydrogen electrolyzers. cost production all these chemicals depends, among other factors, on develop more active selective catalysts. However, order search for materials using computational...
While nitrite reduction proceeds on surfaces with less than three contiguous Pt(111)-sites, the nitrate is inhibited these conditions.
