The potential of the electron for the serial oxygen reduction reaction is calculated by DFT in an aqueous solution in the presence and absence of Cu(acac)2 complex. The study provides interesting information about the rational design of complex-semiconductor hybrid photocatalysts and cathodes for polymer electrolyte membrane fuel cells.
Gold nanoparticle-loaded rutile TiO2 with a bimodal size distribution around 10.6 nm and 2.3 nm (BM-Au/TiO2 ) was prepared by the deposition precipitation and chemical reduction (DP-CR) technique. Visible-light irradiation (λ>430 nm) of the BM-Au/TiO2 plasmonic photocatalyst yields 35 μm H2 O2 in aerated pure water at irradiation time (tp )=1 h, and the H2(More)
Light-driven H+, Na+ and Cl- pumps have been found in eubacteria, which convert light energy into a transmembrane electrochemical potential. A recent mutation study revealed asymmetric functional conversion between the two pumps, where successful functional conversions are achieved exclusively when mutagenesis reverses the evolutionary amino acid sequence(More)
Catalytic activity of gold nanoparticle (NP)-loaded metal oxide semiconductors (Au/MOs) for H(2)O(2) decomposition and chemoselective oxidation of cinnamyl alcohol to cinnamaldehyde strongly depends on both the kind of the MO-supports and the Au particle size, and Au/SrTiO(3) exhibits an extraordinary high level of activity for the H(2)O(2) decomposition(More)
Mesoporous TiO2 nanocrystalline film was formed on fluorine-doped tin oxide electrode (TiO2 /FTO) and gold nanoparticles (NPs) of different sizes were loaded onto the surface with the loading amount kept constant (Au/TiO2 /FTO). Visible-light irradiation (λ>430 nm) of the Au/TiO2 /FTO photoanode in a photoelectrochemical cell with the structure of(More)
Au and Pt nanoparticles with varying mean particle size and comparable loading amounts were loaded on the surface of TiO2 (Au/TiO2 and Pt/TiO2, respectively). The photocatalytic activities of Au/TiO2 and Pt/TiO2 for the oxygen reduction reaction (ORR) in an aerated aqueous solution containing 4% ethanol were compared under ultraviolet-light irradiation at(More)
