We have successfully built a general framework to comprehend the structure-selectivity relationship in ethanol electrooxidation on platinum by density functional theory calculations. Based on the reaction mechanisms on three basal planes and five stepped surfaces, it was found that only (110) and n(111) × (110) sites can enhance CO2 selectivity but other non-selective step sites are more benefi...

We report nanostructure electrodes for methanol electrooxidation by means of the co-sputtering deposition method. The Pt-WC-WO(3) three-phase electrode has higher I(f)/I(b) and oxidation current density i.e. improved electrocatalytic activity in comparison with those of pure Pt and two-phase electrodes because of both catalysis of tungsten carbide and size-control by tungsten oxide.

By using Triton X-114 as structure-director and weak binding stabilizer, ultrathin Au, Pd and Pt nanowires are synthesized in seconds by reduction of inorganic metal precursors with KBH(4) in aqueous phase. The nanowires show high catalytic activity and long-term stability toward electrooxidation of alcohols.

A two-dimensional continuous Pt island network was successfully synthesized by pulse-potentiostatic electrodeposition on a flat silicon substrate, which showed markedly enhanced catalytic activity toward methanol electrooxidation and high CO tolerance, probably due to the synergistic effect of the Pt island catalyst and surrounding SiO(2) surface layer.

Porous Pt-Ni-P composite nanotube arrays (NTAs) on a conductive substrate in good solid contact are successfully synthesized via template-assisted electrodeposition and show high electrochemical activity and long-term stability for methanol electrooxidation. Hollow nanotubular structures, porous nanostructures, and synergistic electronic effects of various elements contribute to the high electr...

The electrooxidation of PFOS can be significantly improved with the simultaneous electrosynthesis ferrate and permanganate from low concentration ambient Fe 2+ Mn in source waters, even presence natural organic matter (NOM).

A detailed understanding of the methanol electrooxidation reaction mechanism is important for further development fuel cells. By modeling on Au(111) using density funct...
