摘　　要：以多孔椰壳碳(CSC)为载体,Ni(NO_(3))_(2)·6H_(2)O为金属源,利用超声-微波一体化方法合成催化剂7%Ni/CSC,对催化剂进行X射线衍射(XRD)、N_(2)吸附、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等表征,发现超声-微波一体化合成的催化剂具有更小的金属粒径。将该催化剂用于催化芳香多羧酸酯的选择性加氢反应时,在加氢反应条件为130℃,3 h和2.0 MPa H_(2)时,邻苯二甲酸二甲酯(DMP)的转化率高达99.8%,产物1,2-环己基-二甲酸二甲酯(DMCD)的选择性为98.8%,并且催化剂的循环使用效果良好。Using porous coconut shell carbon(CSC)as the support and Ni(NO_(3))_(2)·6 H_(2)O as the metal source,the 7%Ni/CSC catalyst was synthesized by the ultrasonic-microwave integrated method.The catalyst was characterized by X-ray diffraction(XRD),N2adsorption,scanning electron microscopy(SEM)and transmission electron microscopy(TEM).The catalyst synthesized by the integration of ultrasonic and microwave has a smaller metal particle size.When the 7%Ni/CSC catalyst was used to catalyze the selective hydrogenation of aromatic polycarboxylates,under the hydrogenation reaction conditions of 130℃,3 h and 2.0 MPa H_(2),the conversion of dimethyl phthalate(DMP)was as high as 99.8%,and the product selectivity to dimethyl 1,2-cyclohexyl-dicarboxylate(DMCD)was 98.8%.Moreover,this catalyst displays a good reusability.
