| 英文摘要 | we present a novel method for preparing an ultra-uniform raney-ni catalyst, which includes melt-quenching, hydrogen treatment and leaching in an alkali solution. the resultant catalyst shows superior activity in the reaction of cyclohexanone hydrogenation. x-ray diffraction (xrd) and xps have been employed to characterize the catalysts. as demonstrated, the pretreatment with hydrogen caused a distinct phase transfer of the ni-al alloys, forming more of the ni2al3 component. in the subsequent leaching process, the ni2al3 component shows high activity and the resultant catalyst exhibits high surface areas and small pores. moreover, metallic al in the hydrogen-pretreated alloy appeared to be leached more easily and thus the aluminium species remaining on the catalyst surface is aluminium oxide predominantly, which serves as a matrix to stabilize active ni species on the surface. copyright (c) 2001 john wiley & sons, ltd. |
