氮镧共掺杂的二氧化钛光催化剂制备及其工艺优化OA北大核心CSTPCD
Preparation and Process Optimization of TiO2Photocatalysts Co-doped with Nitrogen and Lanthanum
采用溶胶凝胶法,以三乙胺为氮源,制备氮和镧共掺杂的TiO2光催化剂.通过X射线衍射(XRD)、扫描电镜(SEM)、紫外-可见漫反射光谱(UV-Vis DRS)对样品进行表征.以亚甲基蓝为目标降解物,在可见光下考察光催化剂的催化活性,结果表明0.8N/La/TiO2具有较好的催化活性,采用正交法对0.8N/La/TiO2催化亚甲基蓝进行工艺优化,影响亚甲基蓝降解的主次顺序为:时间>亚甲基蓝初始浓度>催化剂用量>反应温度,该反应的最…查看全部>>
N and La co-doped TiO2nanocatalysts were successfully synthesized through a sol-gel method by using triethylamine as nitrogen source.The products were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM)and UV-vis diffuse reflectance spectroscopy(UV-Vis DRS).The photocatalytic activities of the N and La co-doped TiO2nanocatalysts were compared by removing methylene blue(MB)under visible light irradiation.The results show that the 0.8N/L…查看全部>>
