Bismuth vanadate (BiVO(4)), which is a visible-light responsive heterogeneous photocatalyst, was combined with homogeneous ruthenium complexes to increase the overall photocatalytic reactivity for water oxidation with a one-electron oxidant, [Co(III)(NH(3))(5)Cl](2+). Photoinduced electron transfer from the excited state of ruthenium(II) complexes to [Co(III)(NH(3))(5)Cl](2+) affords ruthenium(...

BiVO4 has shown great potential as a semiconductor photoanode for solar water splitting. Significant improvements made during recent years allowed researchers to obtain a photocurrent density of up to 4.0 mA cm(-2) (AM1.5 sunlight illumination, 1.23 VRHE bias). For further improvements of the BiVO4 photoelectrodes, a deep understanding of the processes occurring at the BiVO4-H2O interface is cr...

Living systems use catalysis to achieve chemical transformations comply with their needs in terms of energy and building blocks. The pH is a powerful means regulate such processes, which also influences synthetic systems. In fact, the sensitivity artificial photocatalysts, as bismuth vanadate, bears strong potential flexibly influencing both motion pattern speed catalytic microswimmers, but it ...

Incorporation of thermally reduced graphene oxide (RG-O) into the metal oxide semiconductor BiVO4 improves its photoactivity by about three times for sulfite oxidation. The enhancement of photoactivity is attributed to reduced electron–hole recombination of BiVO4 using the RG-O as a conductive matrix in the composite photocatalyst. Photoelectrochemical behavior of the BiVO4 and RG-O/BiVO4 compo...

We report the optimized synthesis and electrochemical characterization of a composite of few-layered nanostructured MoS2 along with an electroactive metal oxide BiVO4. In comparison to pristine BiVO4, and a composite of graphene/BiVO4, the MoS2/BiVO4 nanocomposite provides impressive values of charge storage with longer discharge times and improved cycling stability. Specific capacitance values...

Abstract In this study, three photoelectrodes with bismuth vanadate (BVO) and oxide (BO) films were deposited on an ITO coated glassy substrate using different routes. Both photoactive when irradiated by light. Notably, the photoelectrode BVO–1/BVO–2/BO film showed improved photoelectrochemical performance compared to BVO–1 BVO–1/BVO–2 films, due synergies involved in process of separation/tran...
