Constructing In 2 S 3 /CdS/N-rGO Hybrid Nanosheets via One-Pot Pyrolysis for Boosting and Stabilizing Visible Light-Driven Hydrogen Evolution.

The construction of hybrid junctions remains challenging for the rational design of visible light-driven photocatalysts. Herein, In 2 S 3 /CdS/N-rGO hybrid nanosheets were successfully prepared via a one-step pyrolysis method using deep eutectic solvents as precursors. Benefiting from the surfactant-free pyrolysis method, the obtained ultrathin hybrid nanosheets assemble into stable three-dimensional self-standing superstructures. The tremella-like structure of hybrid In 2 S 3 /N-rGO exhibits excellent photocatalytic hydrogen production performance. The hydrogen evolution rate is 10.9 mmol·g -1 ·h -1 , which is greatly superior to CdS/N-rGO (3.7 mmol·g -1 ·h -1 ) and In 2 S 3 /N-rGO (2.6 mmol·g -1 ·h -1 ). This work provides more opportunities for the rational design and fabrication of hybrid ultrathin nanosheets for broad catalytic applications in sustainable energy and the environment.
