摘要：

In this work, a series of CdS/g-C3N4 nanocomposites with varying wt% CdS were prepared via an in-situ hydrothermal synthesis method. 10 wt% CdS/g-C3N4 nanocomposites displayed the highest rate of hydrogen evolution via photocatalytic water splitting. The H-2 evolution rate of 10 wt% CdS/g-C3N4 is 21 times greater than pure g-C3N4 and 4 times greater than that of pure CdS. Key factors responsible for the enhanced photocatalytic activity can be attributed to the improved charge separation and increased surface area of CdS/g-C3N4 nanocomposites. These findings may serve as a platform for the fabrication of other photocatalytic multi-material nanocomposites in the future. (C) 2019 Elsevier B.V. All rights reserved.
