Abstract

Amorphous Ni50Pd40Si10 alloy powder was prepared by mechanical alloying. The surface states and catalytic activities of amorphous and crystalline Ni50Pd40Si10 alloy powder pretreated with hydrofluoric acid (HF) solution were studied. The results show that amorphous Ni-Pd-Si alloy powder was easily prepared by mechanical alloying. After treating with HF solution, the number of Pd atoms on the surface of amorphous Ni–Pd–Si powder was obviously higher than that of the crystalline alloy and catalytic activity of amorphous Ni–Pd–Si powder was higher than that of the crystalline one by three times.
