摘要
通过溶胶-凝胶法制取掺杂三氧化钨的纳米TiO2复合光催化剂,并通过对染色剂曙红Y进行光催化降解,讨论催化剂用量、加入氧化剂H2O2量等因素对光催化剂降解效率的影响。研究结果表明:在酸性环境的条件下,加入催化剂量为0.15g、双氧水用量为2mL时复合光催化剂有较好降解效果。
The composite photocatalyst WO3- TiO2 is prepared by sol-gel methoed. The photocatalytic degradation of WO3-TiO2 for Eosin Dye Y has been researched. The effect of PH, the amount of catalyst and amount of H2O2 have been investigated. The better conditions are the catalyst 0.15g/100mL and H2O2 2mL/100mL.
