Fig. 3. (A) Influence of the SiO2 content in Ag/AgCl@SiO2-x. (B) Influence of light intensity on CO evolution over Ag/AgCl@SiO2-4.1%. (C) CO evolution of the photocatalyst Ag/AgCl@SiO2-4.1% at different reaction times. (D) Control experiments in the absence of light, the Ag/AgCl@SiO2-4.1% photocatalyst, CH4 and CH4/O2. The amount of every catalyst used in the photoreaction is 10 mg.
