Fe3+掺杂TiO2溶胶的低温制备及其光催化性能OA北大核心CSCDCSTPCD
Study on the Photocatalytic Activity of Fe3+-doped TiO2 Synthesized at Low Temperature
采用溶胶-凝胶法在低温下制备出Fe3+掺杂TiO2( Fe3+/TiO2)溶胶,研究Fe3+掺杂对TiO2催化性能的影响,用TG/DTA技术分析TiO2粉末的热分解过程,用XRD、TEM等表征Fe3+掺杂对TiO2晶型、晶粒尺寸、晶粒形貌的影响,结果表明:Fe3+掺杂会对纳米TiO2晶粒的粒径及晶体形貌产生影响,抑制TiO2晶型由锐钛矿向金红石的转变.将亚甲基监作为目标污染物进行光催化降解试验,紫外-可见漫反射吸收光谱分析表明:经适量Fe3+掺杂…查看全部>>
The Fe3 + -doped titania sol were synthesized at low temperature by sol-gel method. Effect of catalytic properties of titania by doping ferric iron was investigated. The heat decomposition of titania powder was analyzed by means of TG/DTA. Effects of doping ferric iron on crystal form, grain size and grain morphology of titania were characterized by XRD and TEM. The results show that doping ferric iron could prohibit crystal transformation from anatase to ru…查看全部>>
