Amorphous Ni-Pd-Si ribbons were partially crystallized by by relaxation treatment thensecondary amorphous Ni-Pd-Si alloy powder was prepared by mechanical milling.Thesurface states of amorphous and crystalline Ni-Pd-Si powders were studied by XRD,TEM,AES and ESCA spectra.The catalytic activities of amorphous and crystalline powders in hydrogenation of styrene was measured.The result shows that the catalytic activityof amorphous Ni—Pd—Si powder was higher than that of crystalline one by 6 times inhydrogenation of styrene. 相似文献
