Abstract ZnS colloid particles were obtained in wide pH range by using different sulfide-generating precursors, namely, thiourea (NH2)2CS, thioacetamide CH3C(S)NH2, sodium thiosulfate Na2S2O3 and sodium sulfide Na2S. Using different types of chemical precipitation technique made it possible to form ZnS nanoparticles with different crystal structure. The influence of pH value of aqueous solutions was shown to play a crucial role in ZnS structure disordering. The structure characterization of the final products was accomplished through X-ray diffraction and transmission electron microscopy. ZnS was formed in the colloidal/nanocrystalline state regardless of the sulfur agent.

化学反应机理对结构无序ZnS胶体颗粒形成的影响

摘要 利用硫脲(NH2)2CS、硫代乙酰胺CH3C(S)NH2、硫代硫酸钠Na2S2O3和硫化钠Na2S等不同的硫化物生成前驱体，在较宽的pH范围内制备了ZnS胶体颗粒。使用不同类型的化学沉淀技术可以形成具有不同晶体结构的 ZnS 纳米颗粒。研究表明，水溶液 pH 值的影响在 ZnS 结构无序中起着至关重要的作用。最终产品的结构表征是通过 X 射线衍射和透射电子显微镜完成的。ZnS 以胶体/纳米晶态形成，与硫剂无关。
