纳米TiO_2/电气石光催化性能的研究

利用溶胶-凝胶法制备纳米TiO2/电气石复合光催化剂,比较了纯TiO2、电气石粉体和复合催化剂的催化活性,并且从负载次数、活性大红溶液初始浓度方面进行了研究.结果表明,复合催化剂对活性大红有一定的降解作用,4g/L复合催化剂投入到初始浓度为20mg/L、体积为30mL的活性大红溶液中,紫外灯照射4h后,降解率可达到72.3%.

Nanometer TiO_2/tourmaline photochemical catalysis performance research

Prepares the nanometer TiO2/tourmaline compound photocatalyst using the sol-gel legal system,compared with pure TiO2,electrical stone powder body and compound catalyst catalytic activity,and from the load number of times,the active scarlet solution initial density aspect had conducted the research.The result indicated that the compound catalyst scarlet had certain degeneration function to activeness,the 4g/L compound catalyst invests to the initial density was 20mg/L,the volume is wan the 30mL active scarle...
