以柠檬酸为螯合剂,十六烷基三甲基溴化胺为表面活性剂,通过ZrOCl2·8H2O与对苯二甲酸(H2BDC)反应制备了同时具有微孔和介孔结构的Zr基金属有机骨架材料(Zr-MOF),并在超临界CO2-甲醇流体中将Ru负载于Zr-MOF上,制备了Ru@Zr-MOF催化剂,采用傅里叶变换红外光谱、X射线粉末衍射、透射电子显微镜、热重分析、N2吸附-脱附、X射线光电子能谱和电感耦合等离子体发射光谱对催化剂进行了表征,研究了该催化剂在苯及其同系物加氢反应中的催化性能,结果表明,Ru纳米金属颗粒均匀地分散在Zr-MOF载体上,平均粒径约为2.3nm,在苯及其同系物的加氢反应中表现出很高的催化活性和稳定性.
