不同形貌Co3O4负载Pt催化剂的硝基苯加氢性能研究

Study on Hydrogenation of Nitrobenzene over Pt Catalysts Supported on CoO with Different Morphologies

利用Co(NO3)2、CoCl2和Co(CH3COO)2为钴源,通过水/溶剂热法或沉淀法制备出了形貌可控的Co3O4立方体、纳米棒、八面体、六角片四种纳米晶体材料,以它们为载体负载Pt制备催化剂,研究了不同形貌Co3O4负载Pt催化剂的硝基苯液相加氢性能。

Using Co(NO3)2, CoCl2 or Co(CH3 COO)2 as the cobalt source, Co3O4 nancubes, nanorods, octahedrons and hexagonal plates were synthesized by hydrothermal or precipitation methods. Pt/Co3O4 catalysts with the different support morphologies were prepared by an incipient wetness impregnation method and tested in liquid phase hydrogenation of nitrobenzene.
