| 中文摘要: |
| 本文以沉积沉淀法制备NiOx/介孔杭锦2#土催化剂，通过X射线粉末衍射，比表面积及孔结构分析，固体紫外可见漫反射等手段对催化剂进行了表征。以H2O2为氧化剂，在汞灯照射下，研究其对光催化苯直接羟基化反应的催化性能，并探讨了镍的负载量，光源等因素对苯直接氧化制苯酚反应的影响。结果表明，随着镍含量的增加，苯酚的选择性和产率先增大后减小。在优化的反应条件下，苯酚的选择性和产率分别为93%和为56%。 |
| 英文摘要: |
| In this paper, we use (CH3COO)2Ni and hangjin 2# clay as raw material for preparing NiOx/meso hangjin 2# clay. NiOx/meso hangjin 2# clay was characterized by X-ray diffraction, nitrogen adsorption–desorption, high-resolution transmission electron microscopy, energy dispersive X-ray analysis, and UV–visible diffuse reflectance spectroscopy. H2O2 and NiOx/meso hangjin 2# clay were respectively used as oxidant and catalyst, we study direct hydroxylation of benzene photocatalytic reaction catalytic properties, and discuss the influence of nickel loading, light on the direct oxidation of benzene to phenol reaction. The result show that with increasing nickel content, selectivity and yield of phenol increased first and then decreased. Under the optimized reaction conditions, selectivity and yield of phenol were 93% and 56% respectively. |
