银锌共掺杂纳米TiO_2的制备及光催化性能

Preparation and Photocatalytic Activity of Ag-Zn Co-doped TiO_2 Nanoparticles

金属离子掺杂纳米TiO2能加强二氧化钛的光催化降解能力。用溶胶凝胶法制备了银锌共掺杂纳米TiO2,并以甲基橙光催化降解为例考察掺杂离子、掺杂量、催化剂加入量等对光催化性能的影响。

Metal ions doped nano-TiO2 can enhance its photocatalytic activity. Ag/Zn ions co-doped TiO2 nanopartieles were prepared by sol-gel process. The effect of dopant ions, dopant amount and catalyst amount on the photocatalytic reactivity of the prepared catalyst was evaluated by degradation of methyl orange.
