中文摘要:
      近年来,非晶态合金由于在催化加氢反应中表现出优良的催化活性和选择性而受到广泛关注[1,2].其中,化学还原法制备的超细N iB非晶态合金具有很高的催化活性,但该类催化剂易于晶化和氧化失活,限制了其工业应用[3,4].因此,提高N iB非晶态合金的稳定性和抗氧化性引起广泛关注.目前,
英文摘要:
      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.
