二氧化钛／活性炭复合材料的制备及光催化降解性能
Preparation and photocatalytic degradation activity of TiO2/activated carbon composites
摘要
Abstract
Three low-temperature preparation methods of anatase titanium dioxide sol were studied, in which the titanium tetrachloride and ammonia were used as raw materials. The prepared titanium dioxide sol was used to dip oxidation of treated activated carbon by impregnation method. The titanium dioxide was characterized by XRD and FT-IR, and the morphologies of activated carbon before and after treatment of TiO2 were measured by SEM. The degradation experiments of methyl orange were also tested. The results show that the surface morphol- ogy and optical activity of the activated carbon when treated with titanium dioxide are improved. The titanium dioxide films on the oxidated activated carbon become much better. The composites of activated carbon and TiO2 show much higher decomposing ability for methylene oragane compared with activated carbon with simple oxidation process only.关键词
