%X TiO2 nanocrystallite photocatalyst doped with Cu by sol-gel method was prepared,the optimal content of Cu in TiO2 was 2.0%(mol).Its photocatalytic activity was determined,and removal effect of formaldehyde investigated by the photocatalytic decomposition of formaldehyde gas in the environmental chamber using a visible lamp.When the dosage of Cu-TiO2 photocatalyst was at 1.5～2.5 g/m3,and initial concentration of formaldehyde gas 1 mg/m3,the degradation of formaldehyde gas in the environmental chamber had the best effect.Compared with a commercially available P25 photocatalyst,the Cu-TiO2 photocatalyst in the visible range had good degradation of formaldehyde,and after repeated use,the photocatalyst was still kept in its good photocatalytic activity.
