Figure 4. (A) Photocatalytic hydrogen production rates of CdS/MN composites with different weight percentages of MN, in which 4 mg composite photocatalyst was used; (B) AQY of CdS/MN composites. 0 wt% refers to CdS, 20 wt% refers to CdS/MN and 100 wt% refers to MN mentioned in the main text. CdS/MN: Cadmium sulfide/molybdenum nitride; AQY: apparent quantum yield.
