High-Temperature Activation of TiO_2 Sol Modified Bamboo Charcoal

The bamboo charcoal was modified by TiO2 sol synthesized by sol-gel process and its high-temperature activation was carried out. The effect of high-temperature activation on the specific surface area, microstructure and photocatalysis activity of bamboo charcoal were investigated. The results show that after TiO2 sol modification and high-temperature activation, the specific surface area of bamboo charcoal increased sharply, and anatase and rutile co-existing TiO2 particles enriched on the surface of bamboo charcoal or its cell wall, which prevented the structure collapse and endowed the photocatalysis activity of bamboo charcoal. It is advantageous to the production of bamboo charcoal and development of new materials with bamboo charcoal as starting materials.
