摘要：

The conversion of extremely hazardous As(III) to less toxic As(V) and subsequent adsorption onto the catalyst surface holds an advisable process for arsenic contaminants treatment. However, the conflictual mechanism of oxidation and adsorptive remains a huge challenge and unexplored for arsenic removal. In this work, a dual regulation platform of C3N4/C3N5.4 molecular heterojunction was well designed and constructed. The optimized C3N4/C3N5.4 exhibited excellent photocatalytic As(III) oxidation rate and As(V) adsorption efficiency under water, fluorosilicic acid and phosphoric acid solutions. ...
