| 摘 要： | 采用低温醇热法制备了具有空壳花状多级结构的ZnIn2S4可见光光催化剂.通过X射线粉末衍射（XRD）、紫外漫反射（DRS）、场发射扫描电镜（FESEM）、透射电镜（TEM）等对催化剂结构和形貌进行了系统表征.考察了不同陈化温度、陈化时间对催化剂光解水产氢性能的影响.结果表明：在不同醇热条件下合成的Pt/ZnIn2S4均具有光解水产氢性能.其中1%Pt/ZnIn2S4-110-24样品具有最好产氢活性,可能与其独特的花状外壳和空腔结构有关.

| Abstract: | Hollow structured flower-like ZnIn2S4visible-light photocatalysts were synthesized by an alcoholthermal method.The structure and morphology of the catalysts were characterized by X-ray powder diffraction(XRD),UV-visible diffuse reflectance spectrum(UV-Vis DRS),nitrogen adsorption-desorption analysis(BET),field emission scanning electron microscopy(FESEM) and transmission electron microscopy(TEM).All the prepared catalysts with different solvothermal temperatures and time demonstrated visible-light photocatalytic activities in water splitting.The 1%Pt/ZnIn2S4-110-24 sample showed the best activity in water splitting reaction,this is possible due to its unique flower-like morphology and hollow structure. |
