Enhanced Photocatalytic H<sub>2</sub> Evolution over ZnIn<sub>2</sub>S<sub>4</sub> Flower-Like Microspheres Doped with Black Phosphorus Quantum Dots

Enhanced Photocatalytic H<sub>2</sub> Evolution over ZnIn<sub>2</sub>S<sub>4</sub> Flower-Like Microspheres Doped with Black Phosphorus Quantum Dots

In this work, black phosphorus quantum dots (BPQDs) were decorated on hexagonal ZnIn<sub>2</sub>S<sub>4</sub> flower-like microspheres to form zero-dimensional/two-dimensional (0D/2D) structures. Interface interactions between the BPQDs and ZnIn<sub>2</sub>S<su...
