摘要
利用平面流铸法制备了Ni2 3 .3Zr6.7Al64 Cu2 .3Ce3 .7非晶合金 ,用碱洗抽Al的方法进行活化以制备具有较大比表面积的Ni基非晶合金催化剂 .利用XRD ,BET ,TEM等手段 ,研究了在不同活化条件下合金比表面积和结构状态的变化 。
Amorphous Ni 23.3 Zr 6.7 Al 64 Cu 2.3 Ce 3.7 (at%) alloy is prepared by melt-spinning method, then activation treatments of leaching Al in hot alkaline solution, are carried out to obtain the Ni-based amorphous catalysts with large specific surface area. XRD, BET and TEM are used to investigate the changes of the specific surface area and the microstructure under different activation condition. A model is set up based on the relation between the specific surface area of amorphous catalyst and the activation time for the first time.
