| 摘 要： | 采用溶胶-凝胶法制备的纳米TiO2对竹炭进行改性,并对改性前后竹炭进行高温活化,分析溶胶改性及高温活化对竹炭比表面积、物相及显微结构、光催化特性的影响机制。结果表明:溶胶改性及高温活化使竹炭的比表面积急剧增大,竹炭颗粒表面和细胞壁上存在锐钛矿型和金红石型共存的TiO2粒子,防止结构塌陷,并赋予竹炭优越的光催化性能。

| Abstract: | 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... |
