采用均匀沉淀法制备了具有立方相的SnZn（ OH）6（ ZHS）空心粒子，然后通过光化学沉积法将Ag＋还原为Ag0粒子负载于其上，制备得到负载Ag纳米粒子的SnZn（OH）6粒子；使用X射线衍射（XRD）、扫描电镜（ SEM）、紫外-可见漫反射（ DRS）等方法对产品进行了表征，并对其在紫外及可见光下降解罗丹明B的光催化活性进行了检测。结果表明，负载金属银粒子的ZHS不仅在紫外光下对罗丹明B的降解能力有显著的提高，而且对可见光也有明显的响应。

SnZn( OH) 6 ( ZHS) hollow cubes were synthesized by a facile self-templated method at room tem-perature.Ag/ZHS particles were prepared by photodeposition of Ag by reduction of Ag +particles under halo-gen tungsten lamp irradiation.The crystalline structure and morphology of the prepared particles were charac-terized by X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), scanning electron mi-croscopy ( SEM) .The results indicated that the particles had almost uniform monoclinic geometry and uniform size.The photocatalytic activity of Ag/ZHS was tested through degradation of RhB.Therein, the hollow Ag/ZHS showed the highest light catalytic performance due to its large BET surface area and high crystallinity. Furthermore, Ag doped ZHS produced crystal lattice defects and benefited the separation of this photoproduc-tion carrier.
