分别以锌离子和氧化锌作为锌源,利用水热法制备了ZnSn(OH)6粒子.锌的存在状态影响反应过程,进而影响了样品的物相、形貌和性能.以锌离子为锌源时,可以得到立方相ZnSn(OH)6空心粒子,若以氧化锌作为锌源,会得到ZnSn(OH)6/SnO2混合相,没有生成空心结构.在相同的制备条件下,制备了ZnO和SnO2作为对比样品.样品的结构、形貌和尺寸采用X射线粉末衍射(XRD)、透射电镜(TEM)和扫描电镜(SEM)等测试手段进行了表征;并以甲基橙为降解对象,研究了不同样品的光催化性能.与ZnSn(OH)6/SnO2混合相、ZnO和SnO2相比,ZnSn(OH)6空心粒子具有很强的吸附能力和大的禁带宽度,表现出优异的光催化性能.
