Abstract

Amorphous red phosphorus modified ZnIn2S4 (ZIS) hollow spheres were synthesized via a simple one-step hydrothermal method. The P-modified ZIS exhibited enhanced photocatalytic activity under visible light (λ > 420 nm) irradiation, and 1 wt% P-ZIS were found to be the optimal performance for both the H2 evolution and X3B degradation. Moreover, the reason for the enhancement of photocatalytic activity was discussed in detail, which is the addition of P not only can broaden the response range of the catalyst in the visible light wavelength range, but also promotes the separation and transfer of photogenerated electrons and holes.
