摘要
以自制的Gemini表面活性剂为软模版,硝酸锌为锌源、硫酸铜为铜源、硝酸镍为镍源,采用水热法制备Cu、Ni共掺杂ZnO。用XRD、SEM-EDX、UV-Vis DRS和PL对样品进行表征。以罗丹明B为模拟污染物,研究了水热时间,水热温度,煅烧时间,煅烧温度,Cu、Ni掺杂量对光催化性能的影响。结果表明:Cu和Ni均掺入到了ZnO晶格中,光催化实验表明,当水热时间8h、水热温度130℃、煅烧温度500℃、煅烧时间3 h,0.8 mg·L^(-1)的1.0%Cu-3.0%Ni/ZnO在250 W高压汞灯灯光照射90 min后对10 mg·L^(-1)罗丹明B溶液的降解率达到96.9%。
An efficient route for the synthesis of Cu and Ni doped ZnO was developed in the presence of Zn（NO3）2, CuSO4 and Ni （NO3）2 with Gemini surfactant as the soft template. Moreover, the photocatalyst was prepared by a hydrothermal method, and its structure was unambiguously configured by XRD, SEM-EDX, UV-Vis DRS and PL as well. In this paper, different influence parameters to synthesize the ZnO photocatalyst were investigated, such as reaction time, temperature, the doping amount of the Cu and Ni. By adopting the newly synthesized photocatalyst in the degradation of model pollutant RhB, the optimal conditions to afford the ZnO were finally developed. The results show that the degradation efficiency could reach 96.9% in the condition that hydrothermal process 130 ℃ for 8 h, calcination 500℃ for 3 h, and 10 mg·L^-1 RhB under the irradiation of 250 W high pressure mercury lamp with 0.8 g-L-1 1.0%Cu-3.0%Ni/ZnO as photocatalyst.
