Enhanced Photocatalytic H(2) Evolution over ZnIn(2)S(4) Flower-Like Microspheres Doped with Black Phosphorus Quantum Dots

In this work, black phosphorus quantum dots (BPQDs) were decorated on hexagonal ZnIn(2)S(4) flower-like microspheres to form zero-dimensional/two-dimensional (0D/2D) structures. Interface interactions between the BPQDs and ZnIn(2)S(4) resulted in optimum effective charge transfer, thereby improving...

Sumario:In this work, black phosphorus quantum dots (BPQDs) were decorated on hexagonal ZnIn(2)S(4) flower-like microspheres to form zero-dimensional/two-dimensional (0D/2D) structures. Interface interactions between the BPQDs and ZnIn(2)S(4) resulted in optimum effective charge transfer, thereby improving the photocatalytic performance of the material. Thus, the 0.2% BPQD–ZnIn(2)S(4) sample showed 30% higher H(2) evolution rates compared to pure ZnIn(2)S(4). This study provides a simple route for the synthesis of photocatalysts. The results obtained herein can pave the way for designing effective catalysts for solar-to-chemical energy conversion and feasible approaches to obtain cheap, clean, and efficient photocatalysts.
