Construction of g-C₃N₄ and FeWO₄ Z-scheme photocatalyst: effect of contact ways on the photocatalytic performance.

ABSTRACT: Photocatalysis has been regarded as an attractive strategy for the elimination of contaminants, but its performance is usually limited by the fast recombination of photogenerated electron-holes. A heterojunction photocatalyst could achieve the effective separation of electron-holes. However, the electrons migrate to the less negative band while holes move to the less positive band, leading to a weakened redox ability. Z-scheme photocatalysis is a feasible way to realize the efficient separation of photogenerated electron-holes without sacrificing the reductive ability of electrons and oxidative ability of holes. In this work, a new Z-scheme photocatalyst, composed of g-C₃N₄ (photocatalyst I), FeWO₄ (photocatalyst II) and RGO (electron mediator), was fabrica
