a, b Photocatalytic methane halogenation efficiency (a) and selectivity (b) of X%Cu–TiO2 toward CH3Cl production. c Mass spectra of 12CH3Cl (m/z = 50) and 13CH3Cl (m/z = 51) produced over 2%Cu–TiO2 via photocatalytic methane halogenation. d Production rates of CH3Cl via photocatalytic methane halogenation over 2%Cu–TiO2 with different amounts of NaCl. e The cyclic test of photocatalytic CH3Cl production over 2%Cu–TiO2. f Photocatalytic production rates of CH3Cl via methane halogenation over 2%Cu–TiO2 using various chlorine sources. The light intensity is 600 mW cm−2 for all the measurements here. Error bars indicate standard deviations.
