负载型杂多酸催化剂的制备及光催化性能研究
Industrial Catalysis(2009)
Abstract
采用浸渍法和微波法相结合,制备负载型杂多酸光催化剂H_3PMo_(12)O_(40)/TiO_2。在紫外光照射下,研究对模拟染料废水酸性蓝溶液的光催化降解的影响。结果表明,H_3PMo_(12)O_(40)/TiO_2比单独的H_3PMo_(12)O_(40)光催化性能好,在初始浓度10 mg·L~(-1)酸性蓝溶液、m(H_3PMo_(12)O_(40)):m(TiO_2)=1:3、催化剂加入量为90 mg·L~(-1)、pH=1.05、30%的H_2O_2用量10 mL·L~(-1)和180 min条件下,脱色率达93%以上。
