Description
Summary:Owing to the anticipated energy crisis, the demand for photocatalytic H2 evolution is also growing. Herein, a hydrothermal process is used to prepare an S-scheme CdS/N-rGO heterojunction system. Different characterizations reveal that robust interfacial contact and integration of CdS and N-rGO effectively promote the surface area, photoresponse, and separation and migration of photoinduced electron-hole pairs, endowing CdS/N-rGO composite an excellent photocatalytic activity. Under visible light illumination, the CdS/N-rGO obtains a promising H2 evolution efficiency of 58.8 mmolh−1g−1, which is nearly 21-times more than that of bare CdS. The prepared composite also exhibits excellent stability in recycling experiments. This work might open up novel ways to design excellent N-rGO-based S-scheme photocatalysts for solar fuel generation.
