摘要
本文分别以石墨烯和钛酸盐为基质,构建三种不同类型的二维片层复合材料应用于有机化学合成和超级电容器电极材料中。首先,在石墨烯表面负载的Au或Pd,能够有效催化heck反应,制备了一种heck反应的高效催化剂。其次,通过水热反应等条件,在石墨烯表面负载Mn O_2,制备一种性能优异的超级电容器电极用材料。最后,通过湿化学法改变层状钛铌酸盐形貌,制备二维介孔钛铌酸盐,并进一步在钛铌酸盐层板间负载Au纳米颗粒,由于介孔材料良好的吸附效果和选择性,该种复合材料能够实现对硝基苯酚催化加氢,该催化材料在对硝基苯酚加氢还原20多次仍达到95%以上的催化效率。
Three kinds of graphene or titanate nanosheets based composites were constructed to apply in organic catalysis and supercapacitors. Firstly, the Pd nanoparticles loaded graphene composites were prepared to used as catalyst in heck reaction with good efficiency. Secondly, flower-Mn O_2 were loaded onto the surface of graphene through hydrothermal method for constructing supercapacitor. Lastly, the porous structure titanate loading Au composites were obtained with facile method, which can be used to catalytic reduction of p-nitrophenol with good cyclicity.
