A novel amorphous Ni-W-P alloy powder was prepared by chem. reduction Its amorphous structure was determine by XRD, DSC and TEM. The XPS of the Ni-W-P powder showed that both nickel and phosphorus existed as elementary state, while tungsten as metallic and oxidized state on the surface. The catalytic activity of amorphous Ni-W-P for the hydrogenation of cyclopentadiene was measured and compared with amorphous Ni-P. The results revealed that by adding a little amount of tungsten in the amorphous Ni-P alloy, its property was greatly changed.
