摘要：Photo-driven nonoxidative coupling of CH4 to produce valuable hydrocarbons is an attractive potential way to alleviate the energy crisis but is still limited by the lower catalytic efficiency. Herein, a Mo-oxide modified zeolite was fabricated by a facile wet-impregnation method and achieved a CH4 conversion rate of 4.10 mu mol g(-1) h(-1) (8.04% conversion of CH4) at 473 K with continuous light irradiation. There is a good volcanic curve between the activity and the content of Mo loading. The effect of heat and light was elucidated, and irradiation was the essential condition for activation of C-H. Combined with experimental and analysis data, regulating the Mo percentage to construct different Mo species and tuning the acidity strength of catalysts are significant for the catalytic activity and stability.
