Solar Water Splitting: Elaborately Modified BiVO 4 Photoanodes for Solar Water Splitting (Adv. Mater. 20/2019)

Photocharged BiVO4 photoanodes for improved solar water splitting

Bismuth vanadate (BiVO4) is a promising semiconductor material for the production of solar fuels via photoelectrochemical water splitting, however, it suffers from substantial recombination losses that limit its performance to well below its theoretical maximum. Here we demonstrate for the first time that the photoelectrochemical (PEC) performance of BiVO4 photoanodes can be dramatically improv...

LaTiO2N/In2O3 photoanodes with improved performance for solar water splitting.

LaTiO(2)N photoanodes for solar water splitting were prepared by electrophoretic deposition and demonstrated the best photocurrents ever reported for this material. Further important enhancement of the performance was obtained by the use of a sputtered In(2)O(3) overlayer.

Reactive Sputtering of Bismuth Vanadate Photoanodes for Solar Water Splitting

Bismuth vanadate (BiVO4) has attracted increasing attention as a photoanode for photoelectrochemical (PEC) water splitting. It has a band gap in the visible light range (2.4−2.5 eV) and a valence band position suitable for driving water oxidation under illumination. While a number of methods have been used to make BiVO4 photoanodes, scalable thin film deposition has remained relatively underexp...

Water Splitting: One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting (Adv. Sci. 1/2017)

Improving BiVO4 photoanodes for solar water splitting through surface passivation.

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...
