The photocatalyst of TiO2/SnO2 compound semiconductor was prepared by improved solgel method.The coupling mechanism and the factors affecting photoc atalytic efficiency were studied by using XRD,gas chromatography,granularity equ ipment and surface photovoltage spectroscopy.TiO2/SnO2 catalysts were employed f or photocatalytic degradation of formaldehyde.The experimental results showed th at phtocatalytic efficiency of TiO2 catalyst was greatly enhanced by adding SnO2 into TiO2,and the optimum content of SnO2 was about 20 ％(mol).According to the particle close packing rule and experimental result,the strong and weak couplin g effect models for TiO2/SnO2 compound semiconductor were proposed.The coupling effect was derived from the close packing structure of the photocatalyst particl es.The critical bourn between enhanced and weaken effect depends on whether the close packing structure is threedimensional or not.The photocatalyst doped wit h SnO2 less than 20 ％(mol) presented a threedimensional structure,which impro ved the activity of the photocatalyst due to effective separation of the photoge nerated carriers.The opposite situation was occurred when content of SnO2 was mo re than 20 ％(mol).
