| 摘 要： | 采用溶胶-凝胶法制备纳米SnO2,通过浸渍法制备CuO-NiO/SnO2光催化材料,采用XRD、UV-Vis DRS、TEM及HRTEM对其结构、形貌及光吸收性能进行表征。在紫外灯照射下,以无水乙醇为电子给体,详细考察了CuO掺杂量、NiO掺杂量、乙醇浓度等对SnO2光催化产氢性能的影响。研究结果表明:5%CuO-7%NiO/SnO2的光催化产氢性能最佳,约是同条件下纯SnO2产氢性能的2.8倍;最优乙醇浓度约为1.2 mol/L。

| Abstract: | The SnO2 nanoparticles were prepared by sol-gel method.The CuO-NiO/SnO2 semiconductor materials were synthesized by impregnation process.The phase composition,morphologies and light absorption ability were further characterized by XRD,UV-Vis DRS,TEM and HRTEM.Using UV light as light source and ethanol as electron donor,the effects of CuO doping content,NiO doping content and ethanol concentration on hydrogen evolution performance have been systematically studied.The results showed that 5%CuO-7%NiO/SnO2 had best photocatalytic H2-production activity,about 2.8 times higher than pure SnO2 under the same conditions.The optimum concentration of ethanol was about 1.2 mol/L. |
