We investigate the possibility of modification of SnS powder through sonochemical synthesis with the addition of an organic ligand. For that purpose, two organic dyes are used, Phenol Red and Anthraquinone Violet. All obtained powders are characterized using XRD, SEM, EDX, FT-IR, and UV-Vis investigations. Synthesized samples showed composition and structural properties typical for sonochemically synthesized SnS. However, investigation with the Tauc method revealed that SnS powder modified with Phenol Red exhibits a significant shift in value of optical bandgap to 2.56 eV, while unmodified SnS shows an optical bandgap value of 2.42 eV. The modification of SnS powder with Anthraquinone Violet was unsuccessful. The obtained nanopowders were utilized as photocatalysts in the process of Metanil Yellow degradation, revealing that SnS modified with Phenol Red shows about 23% better performance than the unmodified one. The mean sonochemical efficiency of the performed synthesis is also estimated as 9.35 µg/W.
我们研究了通过添加有机配体利用声化学合成法对硫化亚锡（SnS）粉末进行改性的可能性。为此，使用了两种有机染料，酚红和蒽醌紫。所有获得的粉末均通过X射线衍射（XRD）、扫描电子显微镜（SEM）、能量散射X射线光谱（EDX）、傅里叶变换红外光谱（FT-IR）和紫外可见光谱（UV-Vis）进行表征。合成的样品显示出典型的声化学合成SnS的组成和结构特性。然而，用陶克（Tauc）方法研究发现，用酚红改性的SnS粉末的光学带隙值显著偏移至2.56电子伏特（eV），而未改性的SnS的光学带隙值为2.42 eV。用蒽醌紫对SnS粉末的改性未成功。所获得的纳米粉末被用作甲基黄降解过程中的光催化剂，结果表明，用酚红改性的SnS表现出比未改性的SnS约23%的更好性能。所进行合成的平均声化学效率也估计为9.35微克/瓦（µg/W）。
