| Abstract: | The amorphous NiB alloy was prepared by chemical reduction and used in the hydrogenation of sulfolene to sulfolane.The used catalyst was treated by acid at different conditions.The catalyst was characterized by ICP, XRD,TEM and SAED.The results shows that the oxide in the deactivated amorphous NiB alloy decreases obviously after the treating with acid(pH=2).The regenerated catalyst exhibits excellent catalytic activity and the amorphous structure is preserved. |
