A g-C3N4-CdS composite catalyst with high visible-light-driven catalytic activity and photostability for methylene blue degradation

- g-C3N4-CdS heterostructure exhibits a higher visible-light photocatalytic activity than g-C3N4 or CdS.
- The large surface area and the synergistic effect result in the enhanced activity of g-C3N4-CdS.
- g-C3N4-CdS photocatalyst effectively inhibits the photocorrosion of CdS.
