In this paper, take natural zeolite, tetrabutyl titanate, ethanol and acetic acid as raw materials,usingsol-gel method, preparating zeolite loading nano titanium dioxide ,zeolite doping nano-oxide photocatalytic materials, then study its performance of degradation of methyl orange.According to explore the different factors which impact the photocatalytic efficiency, design and conduct the orthogonal test, finally determine the optimal conditions, that anhydrous ethanol: tetrabutyl titanate: the volume ratio of glacial acetic acid is 30 ml: 25 ml: 15 ml, zeolite particle size is 800 mesh, calcination temperature is 300℃, glacial acetic acid addition level is 15 ml.By experiment and test characterization, carry out the doping tests of Fe3+, Zn2+, N, and La3+and the ions doping test of Fe3+ with La3+. Photocatalytic experimental results show that the different types, different amounts of ions have different levels of impact on photocatalysis, coparing with undoped ions, photocatalytic activity of doped ions improves than before.
