本网讯 近日,石化新材料与资源精细利用国家地方联合工程实验室尹笃林教授课题组刘俊逸博士的论文在发表Catalysis Communications杂志,全文摘要如下:A series of Fe2O3doped SBA-15 materials were preparedviaan equivalent-volume impregnation method. The resultant Fe2O3-containing SBA-15 materials showed good performance in phenol methylation. Under the same conditions, the mesoporous catalyst with 5 wt.% Fe2O3showed the superior catalytic activity to that of pristineα-Fe2O3even at lower reaction temperature (320 °Cvs.350 °C). The elevated catalytic activity observed for the mesoporous catalyst could be due to high level dispersion of Fe2O3species in the mesoporous framework. Furthermore, the mesoporous catalyst possessed long lifetimes, which could be used continuously for 2000 h without significant loss of activity.
