Abstract

The diatomite as the main raw material and TiCl₄ as the source of titanium,hydrolytic precipitation method was used to prepare a new type of environmentally friendly material-nano-TiO₂/diatomite-based porous ceramsite composite material.Its formaldehyde removal effect in a 1 m³ environmental 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 purifier core, it will play a positive role in solving the air pollution problem of newly renovated houses.
- diatomite-based porous ceramite,
- air purifier core,
- photocatalytic property,
- removal rate of formaldehyde
