锌铜复合氧化物光催化降解甲基对硫磷

Photocatalytic Degradation of Methylparathion by Zn Cu Coupling Oxide

采用共沉淀法制备了锌铜复合氧化物光催化剂,并通过其光催化降解甲基对硫磷农药。结果发现,锌钢复合氧化物能有效地利用空气中的氧,使甲基对硫磷快速光降解,基中ZnO是一个较好的氧化物半导体,而CuO仅起到助催化作用。最后还讨论了催化剂制备、光降解条件诸因素对光降解甲基对硫磷效果的影响。

Taking Zn Cu coupling oxide as a photocatalyst for photocatalytic degradation of methylparathion(MP) aqueous solution was discussed and showed that Zn Cu coupling oxide could photodegrade MP quickly by using oxygen of air effectively. ZnO is a good oxide semiconductor but CuO is only used as a aid catalyst. The various factors that influence the photocatalytic degradation of MP were also discussed.
