Photocatalytic removal of formaldehyde under ultraviolet radiation has been studied using attapulgite base composite photocatalysts（ATP-SnO2-TiO2）,which were synthesized by an in situ sol-gel technique with a carrier of attapulgite.The composites were characterized by X-ray diffraction（XRD）,transmission electron microscopy（TEM） and other analytical techniques.The effects of preparing conditions on the physical characterization and the photoactivity were investigated,and photoability of different composite photocatalysts were also discussed in detail.Results showed the photoability of ATP was improved significantly by loading SnO2-TiO2,when the proportion of TiO2 was 50%,quality ratio of SnO2/ TiO2 was in 1∶4 and the sample was treated at 800 ℃,the photoability was larger.The degrationg rate on the formaldehyde of 30 mg/L can amount to 99% above after three hours,the composite photocatalyst showed excellent photocatalytic properties.
