英文摘要	a series of ni-promoted w2c catalysts was prepared by means of a post-impregnation method and evaluated for the catalytic conversion of cellulose into ethylene glycol (eg). quite different from our previously reported niw2c/ac catalysts, which were prepared by using the co-impregnation method, the introduction of ni by the post-impregnation method did not cause catalyst sintering, but resulted in redispersion of the w component, which was identified and characterized by means of xrd, tem, and co chemisorption. the highly dispersed ni-promoted w2c catalyst was very active and selective in cellulose conversion into eg, with a 100?% conversion of cellulose and a 73.0?% yield in eg. the underlying reason for the enhanced catalytic performance was most probably the significantly higher dispersion of active sites on the catalyst.
