摘　　要：使用乙二醇、醋酸锌、钼酸铵以及阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)通过溶剂热方法合成了形貌可控的锌酞菁纳米催化剂,研究了催化剂的表面形貌特征、可见光吸收性能以及光催化活性,探索了在CTAB存在下锌酞菁的形貌形成机理。结果表明:在CTAB存在下溶剂热合成的锌酞菁颗粒为直径约100nm的小球,表面呈现出褶皱结构,球与球之间存在空隙并且均匀分布,在2θ=33.2°衍射角处有一个较明显的衍射峰,可见光催化活性较好,在光照条件下8h可以将RhB染料完全降解,并且推测出纳米催化材料的形成过程是胶束形成过程。Nanocrystalline zinc phthalocyanine （ZnPc ） catalyst with controllable morphology was synthesized by solvothermal method in the presence of ammonium molybdate,zinc acetate,ethylene glycol and cationic surface active agent cetyltrimethyl ammonium bromide （CTAB）.The surface morphology, visible light absorption properties and photocatalytic activity of the catalyst were studied, and the morphology formation mechanism of CTAB-assisted ZnPc was investigated.The results show that the ZnPc particle synthesized in the presence of CATB is the nanosphere with the diameter of about 100nm;the surface shows wrinkle structure;voids exist between the nanospheres.There is an obvious diffraction peak at the diffraction angle of 2θ= 33.2°.The visible-light catalytic activity is good.The nanometer catalyst could completely degrade RhB under visible light irradiation for 8 h.It is inferred that the formation process of CTAB-assisted ZnPc is micelle formation process.
