纳米Cu_2O光电催化降解活性艳红X-3B的研究

Photoelectrocatalytic Degradation Reactive Brilliant Red X-3B by Using Nano-Cu_2O

以纳米氧化亚铜为催化剂,光电催化降解活性艳红X-3B,考察了初始浓度,催化剂用量,起始p H和电解质种类及浓度等因素对光电催化降解活性艳红X-3B的影响。结果表明,在高压汞灯照射下,外加偏压3.0 V,常温25℃,光催化剂Cu2O用量为2.0 g/L,p H为3,氯化钠电解质0.05 mol/L,降解70 m L 30 mg/L的活性艳红60 min,其降解率可以达到92.78%。

In the experiment, cuprous oxide as catalyst to photoelectrocatalytic degrades reactive brilliant red X-3B. The effection of initial concentration, catalysts, initial pH, different electrolysts and electrolyst concentration were studied. The results show that under the high pressure mercury light, bias voltage 3.0 V, 25℃, concentration of catalyst is 2.0 g/L, initial pH=3, 0.05 molFL NaCI, degrade 70 mL 30 mg/L reactive brilliant red X-3B, the degradation rate can reach 92.78 % in 60 min.
