Abstract
A novel copper phthalocyanine/mordenite zeolite (CuPcs/MOR) photocatalyst was synthesized and tested to be a good photocatalyst for NOx removal. With CuPcs0.85/MOR2 composite as catalyst, the degradation rate of NO2 can reach 71.4% under irradiation for 2 h than that of pure CuPcs, attributing to the synergistic effect between them. The process of NOx photocatalytic degradation was discussed, indicating that the MOR with adsorption property not only increased the active sites of CuPcs but also accelerated the charge transfer. A small amounts of copper oxide species are produced during the synthesis, forming co-catalyst with copper phthalocyanine in the system to eliminate nitrogen oxides.
