摘要
采用水热法合成了WO3/Cu2O粉末,并对其进行了X射线粉末衍射(XRD)表征。以苯酚为降解目标,考察了催化剂用量、WO3的负载量、光源、空气流量及苯酚初始浓度等工艺条件对其降解率影响。结果表明:当WO3的负载量为10%时其光催化活性较好,在空气流量为150mL/min,WO3/Cu2O的加入量为0.75g/L,400W金卤灯光照180min的条件下,可使初始浓度为6mg/L的苯酚降解率达98%以上。
The WO3/Cu20 powder was synthesized by hydrothermal method,and characterized by X ray powder diffraction （XRD）.Taking phenol as degradation target,the effects of the amount of catalyst,the load of WO3,light source,air flow rate and initial phenol concentration conditions on the degradation rate have been investigated.The results show that the photocatalytical activity is preferable when WO3 content is 10％.The degradation rate of phenol with the initial concentration of 6 mg/ L can be above 98％ when air flow is 150 mL/min,WO2/Cu2O dosage is 0.75 g/L,metal halide light is 400 W and irradiation time is 180 min.
