Abstract
Fabricating a doped bismuth vanadate electrode includes spray coating a substrate with an aqueous solution with vanadium-containing anions and bismuth-containing cations to yield a coated substrate, heating the coated substrate to form crystalline bismuth vanadate on the substrate, and doping the crystalline bismuth vanadate with lithium ions to yield a doped bismuth vanadate electrode.
