摘要
双金属催化剂是一类重要的多相催化剂。其中d电子在催化活性方面起着重要的作用.本文在Co_3[Fe(CN)_6]_2的工作基础上,进一步研究了该配合物在硅胶、氧化铝、以及氧化镁上的热性质,同时考察了CN^-在Co-Fe体系双端基配位的活化加氢,探讨了载体的影响.
This study deals with properties and thermal reactions of Co_3 [Fe(CN)_6]_2 supported onsilica, γ-alumina and magnesia. The final solid products of thermal decomposition in hy-drogen atmosphere consisted of Co-Fe alloy and highly dispersed surface Fe(Ⅱ)ions.HCNwas formed on silica and γ-alumina as a result of (CN)_2 hydrogenation. Neither HCN norNH_3 was produced on magnesia because of the basicity of the support. Thus HCN maybe considered as an intermediate of the hydrogenation process from(CN)_2 to NH_3.
