(Invited) Chemical and Photochemical Transformations of Bismuth
Vanadate and Catalyst Integration for Stable
Photoanodes.
«Today, bismuth
vanadate is one of the best materials available for constructing
photoanodes,» said Sharp.
Our joint theory - experiment effort has successfully identified new earth - abundant copper and manganese
vanadate complex oxides that meet highly demanding requirements for
photoanodes, substantially expanding the known space of such materials.
Employing a strategic combination of detailed electronic structure calculations, combinatorial materials synthesis, and both traditional and high - throughout photoelectrochemistry measurements, the JCAP team identified earth - abundant copper and manganese
vanadate complex oxides that meet highly demanding requirements for
photoanodes: low band gap energy, stability under highly oxidizing conditions, and valence band alignment with respect to OER.
The scientists focused on bismuth
vanadate, a thin - film semiconductor that has emerged as a leading candidate for use as a
photoanode, the positively charged part of a photoelectric cell that can absorb sunlight to split water.
