Black Phosphorus Quantum Dots

Efficient charge separation of Cu7S4/ZnIn2S4 and the carrier transfer facilitator of BPQDs are responsible for the enhanced H2 production, resulting in the H2 evolution rate of 885 μmol g−1 h−1, 6.8 times higher than that of pristine ZnIn2S4.

Effective Charge Transfer

In this work, black phosphorus quantum dots (BPQDs) were decorated on hexagonal ZnIn2S4 flower-like microspheres to form zero-dimensional/two-dimensional (0D/2D) structures. Interface interactions between the BPQDs and ZnIn2S4 resulted in optimum effective charge transfer, thereby improving the photocatalytic performance of the material. Thus, the 0.2% BPQD–ZnIn2S4 sample showed 30% higher H2 evolution rates compared to pure ZnIn2S4. 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.

Photocatalytic H2 Evolution

The capture of the photogenerated holes by the deposited Ni(OH)2 contributes to the efficient charge separation, allowing more photogenerated electrons to be left on ZnIn2S4 to reduce H+ to H2.
