Water oxidation of visible-light-responsive bismuth-yttrium oxychloride promoted by a dual-ion doping strategy for assembly of Z-scheme overall water splitting

A novel dual ion doping strategy to modulate the structure of Bi 2 YO 4 Cl is introduced and the first successful visible-light-responsive oxyhalide-based Z-scheme OWS system based on the colorless IO 3 − /I − shuttle redox pair is fabricated.
