摘要
用机械合金化法制备了负载型非晶态Ｎｉ－Ｎｂ／ＳｉＯ２纳米粒子，粒径约为１０ｎｍ，硅胶的加入不仅大大加速了金属合金化的过程，而且使金属粒子比较均匀地分散在ＳｉＯ２中。这种材料比之单纯的纳米粒子更适合于作为催化剂。
The supported nano-particles amorphous Ni-Nb/SiO2 with about 10urn dimension was prepared. The addition of silica gel not only accelerated the alloying process greatly, but also made the metal particles dispersed more homogeneously in the silica gel. Compared with the pure Ni-Nb nano-particles, this material is more suitable as catalyst.
