| 摘 要： | 以硫脲为硫源，采用燃烧法制备了Zn0.5Cd0.5S半导体光催化材料．利用X-射线粉末衍射仪（XRD），扫描电子显微镜（SEM），紫外-可见分光光度计（UV-vis）对样品进行了表征．研究了硫脲加入量对Zn0.5Cd0.5S的结构、形貌、吸收光谱及光催化性能的影响．结果表明：虽然硫脲的使用量对于制备样品的形貌没有明显的影响，它对于样品的结构及光催化性能有着显著地影响．当硫脲的使用量为4倍时所制备的Zn0.5Cd0.5S为六方与立方两种晶相的混合相，其对于亚甲基蓝的光催化性能最好．

| Abstract: | Zn0.5 Cd0.5 S powders were synthesized by a combustion method, using the thiourea as the sulfur source. The as-synthesized samples were characterized by X-ray powder diffraction （XRD）, Scan- ning electron microscopy （SEM）, ultraviolet-visible spectrophotometer. The influences of amount of thiourea on the structure, UV-vis absorption and photocatalytic properties of Zn0.5 Cd0.5 S with different adding amounts of thiourea were studied. The results show that using amount of thiourea has no signifi- cant effect on the morphology of samples. When the amount of thiourea is 4 times, the phase of Zn0.5 Cd0.5 S is the mixture of hexagonal and cubic phases, which exhibits the best photodegradation perform- ante for methylene blue. |
