TiO2/石墨烯复合材料的制备及其光催化性能
Preparation and Photocatalytic Activity of TiO2/Graphene Composites
摘要
Abstract
TiO2/Graphene composites (TiO2/GR) synthesized by one-step hydrothermol method using graphene oxide (GO) and tetra-n-butyl titanate. Influences of different dosages of GO, reaction temperature and time on the photocatalytic activity of TiO2/GR were studied. Crystal structure, particle size, morphology and specific surface area of TiO2/GR were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brumauer-Emmett-Tller (BET) analysis. Results show that the optimum conditions for TiO2/GR as follows: dosage of GO, reaction temperature and time of the composites are lmg, 180℃ and 16 h, respectively. TiO2 in composites is anatase and average diameter is about 18 nm. Specific surface area of the TiO2/GR is 170 m2/g and average pore diameter is 12.45 nm. Under visible light (λ＞420nm), activity of photodegradating RhB by TiO2/GR is better than that of TiO2 obtained under the same conditions.关键词
