a) UV‐DRS spectra of Cu0.1Pt0.5/PC‐50, Pt0.5/PC‐50, Cu0.1/PC‐50, and PC‐50. b) C2 production of photocatalytic OCM over Cux/PC‐50 (x=0.05, 0.1, 0.2, 0.3, 0.4; reaction conditions: O2/CH4=1:240, GHSV=1200 h−1, 10 % of CH4, 365 nm LED 20 W, 40 °C). c) C2 production and selectivity of photocatalytic OCM over Cu0.1Pty/PC‐50 (y=0.1, 0.5, 1.0, 1.5, 2.0 wt %), Cu0.1/PC‐50, PC‐50, Pt0.5/PC‐50, and Pt0.5Cu0.1/PC‐50 (reaction conditions: O2/CH4=1:400, GHSV=2400 h−1, 10 % of CH4, 365 nm LED 40 W, 40 °C). d) Stability test of photocatalytic OCM over Cu0.1Pt0.5/PC‐50. GHSV=gas hourly space velocity.
