Preparation of Fe-Ni/C Composite Catalyst for the Hydrazine Hydrate Catalytic Reduction

摘要：

　　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-chloronitrobenzenes hydrazine hydrate catalytic reductions as the examples.Experimental results showed that the optimal conditions were as follows:preparation temperature is 50 ℃,catalyst carrier is nitric acid treated activated carbon,w(Fe) is 5% and w(Ni) is 0.2%.During the preparation,ultrasonic treatment is also helpful to improve catalytic efficiency of Fe-Ni/C composite catalyst.The newly prepared Fe-Ni/C composite catalyst has combined the advantages of noble metal catalyst and iron-based catalyst and features good reduction selectivity and high catalytic efficiency.
