Chromium (Cr) typically exists in either trivalent and hexavalent oxidation states in drinking water,i.e.,Cr(Ⅲ) and Cr(Ⅵ),with Cr(Ⅵ) of particular concern in
Z-scheme photocatalysts,with strong redox ability,have a great potential for pollutants degradation.However,it is challenging to construct efficient Z-scheme ph
