摘要
采用水热法制备了高岭土-Cu2O光催化剂,并且借助XRD、SEM等测试手段对其进行了表征。以对苯二酚为研究对象,考察了光源、催化剂用量、高岭土负载量、对苯二酚浓度等因素对光催化降解对苯二酚的影响。结果表明:以400 W金卤灯作为光源,在20 mL对苯二酚溶液中加入15%高岭土-Cu2O 0.1 g,光照反应180 min后,可使初始浓度为5mg/L的对苯二酚降解率达到97%以上。
The kaolin-Cu2O photocatalyst was prepared by hydrothermal method, and characterized by XRD, SEM, etc. The effect of light source, catalyst dosage, kaolin loading and concentration of hydroquinone on photocatalytic degradation of hydroquinone was investigated. The results showed that, with 400 W metal halide lamp as light source, adding 15% kaolin-Cu2O 0.1 g into 20 mL hydroquinone solution, the degradation rate of hydroquinone with initial concentration of 5 mg/L was more than 97% after light reaction with 180 min.
