CuO/TiO2/ZnO三元复合催化剂的研制和性能研究

Preparation and Properties of CuO/TiO2/ZnO Ternary Composite Catalyst

通过水热合成法制备CuO/TiO2/ZnO三元复合催化剂.利用XRD、SEM、Uv-vis等对CuO/TiO2/ZnO复合材料的样品进行表征、性能的测试.研究结果表明,CuO/TiO2/ZnO复合粉体对日光与紫外光的吸收强度高于单体粉体.通过表征和性能对比发现,TiO2/CuSO4/ZnO的效果没有CuO/TiO2/ZnO的复合效果好,另外模拟了在太阳光下测试了它们对亚甲基蓝的催化吸附性能,具有较好的应用前景.

CuO/TiO2/ZnO ternary composite catalyst was prepared by hydrothermal synthesis.The samples of CuO/TiO2/ZnO composite were characterized by XRD,SEM and UV-Vis.The results show that the absorption intensity of CuO/TiO2/ZnO composite powder is higher than that of monomer powder.Through the comparison of characterization and performance,it is found that the effect of TiO2/CuSO4/ZnO is not as good as the composite effect of CuO/TiO2/ZnO.In addition,the catalytic adsorption performance of TiO2/CuSO4/ZnO to methylene blue is simulated and tested under the sun light,which has a very good application prospect.
