RESUMO
This paper studied preparing photocatalyst supported on natural clinoplilolite, photocatalysis degrading to methyl orange solution as photocatalysis function test, solar as light resource, explored the synthesize condition and affect factors of its catalysis activity. The capability of catalyst was evaluated by decolor rate and COD removal rate. The samples was described by XRD, IR and specific surface area. Studied result showed that catalyst prepared by combination of tetrabutyl titanate and natural clinoplilolite dryed under 120 degrees C for 6 hours then calcined under 200 degrees C had the best photocatalysis activity. Degrading rate of methyl orange solution increased with the quantity of TiO2/zeolite and additional oxidant H2O2 increasing, but superfluous H2O2 can also restrain the photocatalysis activity of titanium dioxide supported on clinoplilolite. Methyl orange solution had the best degrading rate as pH value between 2 to 5.
