Hydrazine hydrate catalytic reduction (HHCR) is a green, eco-friendly method to reduce aromatic nitro compound to aromatic amine. Fe-Ni/C composite catalyst for HHCR was prepared. Preparation conditions of Fe-Ni/C composite catalyst were investigated taking o-chloronitrobenzene's hydrazine hydrate catalytic reductions as the examples. Experimental results showed that the optimal conditions were as follows: preparation temperature is 50°C, catalyst carrier is nitric acid treated activated carbon, w(Fe) is 5% and w(Ni) is 0.2%. During the prepar...
