摘要
本文考察了不同负载量的Fe/SBA-16催化剂对苯选择氧化制备苯酚催化活性的影响。运用小角XRD、N2吸附及紫外漫反射光谱对催化剂的结构和催化剂表面活性物种进行研究。结果表明:Fe/SBA-16催化剂保持了SBA-16介孔分子筛的三维立方的孔道结构,高分散的铁物种是催化反应的活性物种。
The activities for hydroxylation of benzene was investigated on different Fe loading of Fe/SBA-16 catalysts.The structure and the dispersion of Fe/SBA-16 catalysts have been characterized by small-angle XRD,N2-physisorption and DRUV-vis spectrum.The results indicated Fe/SBA-16 catalysts retained the cubic cage-like pore structure of SBA-16.The activities of benzene hydroxylation enhanced by highly dispersed Fe species.
