Abstract：The diatomite as the main raw material and TiCl4as the source of titanium,hydrolytic precipitation method was used to prepare a new type of environmentally friendly material—nano-TiO2/diatomite-based por-ous ceramsite composite material.Its formaldehyde removal effect in a 1 m3environmental chamber was tested. The results showed that the composites had good removal effect for formaldehyde under ultraviolet light,and the removal rate of formaldehyde was the highest 97.8% at 120 min. If the composites is used as an air purifi-er core,it will play a positive role in solving the air pollution problem of newly renovated houses.
