| 摘 要： | 采用非水体系溶剂热法制备了(001)面暴露的锐钛矿相F/TiO2纳米光催化剂.结果表明,F的掺杂对TiO2纳米单晶的形成影响很大.一方面,F离子作为晶面导向剂稳定(001)晶面,形成(001)面暴露的锐钛矿相TiO2;另一方面,F离子也起到稳定剂作用,抑制纳米粒子的快速生长.以光催化降解甲基橙为模型反应比较了不同F/T...

| Abstract: | F/TiO2 nanocrystals with exposed(001)facets were synthesized by a nonhydrolytic solvothermal route.The influence of F ions on the formation process was investigated in detail.The F ions function as a crystal-face directing agent and a stabilizing agent.The photocatalytic activities of the F/TiO2 and commercial P25 samples were determined by the degradation of methyl orange.The influencing factors and active species in the degradation process are discussed after particular characterization and experiments wi... |
