Abstract

Molybdenum disulfide /reduced Graphene Oxide /Polyaniline nanocomposites (NCs) was prepared via a two-step synthesis procedures involving hydrothermal and in-situ chemical polymerization techniques. The morphological analysis revealed a well-interconnected structure. X-ray diffraction and Raman spectroscopy revealed the effective formation of the nanocomposites, while Ultraviolet-diffuse reflectance spectroscopy demonstrated enhanced visible light absorption. The degradation rates were up to 96.59% for Methylene Blue, 70.24% for Rhodamine Blue, and 46.03% for Methyl Orange under sunlight light irradiation. The antimicrobial activity of the NCs against various strains, including Escherichia coli, Candida Albicans, and Staphylococcus aureus showed that the prepared nanocomposite possesses better effectiveness against Candida Albicans.

聚苯胺纳米杂化的花状（金盏花）MoS2-warped rGO 异质结构在抗菌和抗污染方面的新用途

二硫化钼/还原氧化石墨烯/聚苯胺纳米复合材料（NCs）是通过水热和原位化学聚合技术两步合成法制备的。形态分析表明其具有良好的互连结构。X 射线衍射和拉曼光谱显示了纳米复合材料的有效形成，而紫外-漫反射光谱则显示了增强的可见光吸收。在日光照射下，亚甲基蓝的降解率高达 96.59%，罗丹明蓝的降解率高达 70.24%，甲基橙的降解率高达 46.03%。纳米复合材料对各种菌株（包括大肠杆菌、白色念珠菌和金黄色葡萄球菌）的抗菌活性表明，所制备的纳米复合材料对白色念珠菌具有更好的抗菌效果。
