摘　　要：采用热分解法制备了三维的亚稳态正交相AgInS_2和六方相CuInS_2花状微米球。通过X射线衍射(XRD),场发射扫描电子显微镜(FESEM)等对样品进行表征,对AgInS_2的光催化性能进行了评估,并借助于热重-差热分析(TG-DTA)等手段研究了亚稳态正交相AgInS_2和六方相CuInS_2花状微米球的生长机理。实验结果表明,反应温度和反应物中金属离子的投料比对生成纯相的MIn S2均有影响,而AgInS_2花状微米球能在可见光下较好地催化降解亚甲基蓝。3D metastable orthorhombic AgInS2 and hexagonal CuInS2 flowerlike microsphere were synthesized by the thermolysis method. The obtained products were characterized by X-ray diffraction （XRD）, field-emission scanning electron microscope （FESEM）, and the photoeatalytic activity of AgInS2 were investigated. Furthermore, the possible growth mechanism of metastable orthorhombie AgInS2 and hexagonal CuInS2 flowerlike microsphere was also proposed by means of thermogravimetric thermogravimetric and differential thermal analysis （TG-DTA）. The results indicated that both the reaction temperature and feed ratio of metallic ion （nM / nIn） had an influence on the formation of pure-phase MInS2, and the prepared AgInS2 flowerlike microsphere could well degrade methylene blue （MB） under visible light irradiation.
