本文主要研究了γ-Al-5O_2载体上Ni-Mo催化剂的表面分散模型.催化剂制备采用先Ni后Mo的二次浸渍方法,XPS实验结果表明活性组份是大致以单层分散在载体表面上.

In this paper, the surface dispersion model of Ni-Mo catalyst on γ-Al-5O_2 was studied.The second impregnation method of Ni after the first Ni was used to prepare the catalyst, and the results of XPS indicated that the active component was dispersed as a single layer on the surface of the support .
