摘要

以Zn(CH3COO)2·2H2O、InCl3·4H2O和l -半胱氨酸为原料，在160℃下反应48 h，采用便捷的一步溶剂热法制备了类似牡丹的ZnIn2S4微球。采用x射线衍射、氮吸附分析、x射线光电子能谱、透射电镜和扫描电镜对晶体结构进行了表征。场发射扫描电镜(FESEM)和透射电镜(TEM)分析表明，产物由牡丹状微球组成，花瓣厚度为~ 30 nm。本文还提出了该产物形成的可能机理。制备的产物对甲基橙有较强的紫外光催化降解活性。

Synthesis and photocatalysis of peony-like ZnIn2S4 microspheres

Peony-like ZnIn2S4 microspheres were successfully synthesized via a convenient one-step solvothermal method by using Zn(CH3COO)2 · 2H2O, InCl3 · 4H2O and L-cysteine at 160 ^°C for 48 h. The crystal structure was characterized by X-ray diffraction, nitrogen sorption analysis, X-ray photoelectron spectroscopy, transmission electron microscopy, and scanning electron microscopy. Field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analyses showed that the products consisted of peony-like microspheres with petals of ∼30 nm in thickness. A possible mechanism for the formation of the product is also proposed in this paper. The as-prepared product showed enhanced UV-light photocatalytic activity for methyl orange degradation.
