Abstract

Tungsten trioxide nanoparticles (WO₃ NPs), Graphene oxide nanosheets (GO NSs), and WO₃-GO (50 mg and 100 mg) nanocomposites (NCs) were successfully synthesized by using precipitation, modified Hummer's and ultrasonication methods, respectively. Various characterization techniques were used to confirm the formation of individual and composite materials. Hydrogen storage, electrochemical, antibacterial and anticancer properties of the synthesized materials were studied. Formation of the composite was confirmed by XRD, Raman and XPS analyses. Surface area and pore size distribution of WO₃ NPs and WO₃-GO NC were studied by using BET analysis. Hydrogen storage capacity of WO₃-GO 50 mg and WO₃-GO100 mg NCs was found to be 1.05 and 2.08 wt%, respectively. XRD, Raman, elemental and TG analyses were used to examine the adsorption and desorption of hydrogen. WO₃-GO NCs showed higher specific capacitance as compared to WO₃ NPs. Antibacterial activity against E. coli, S. aureus bacteria and anticancer effect against human breast cancer cells of WO₃ NPs and WO₃-GO NC were examined. Based on the studies, it is evident that the inclusion of GO enhanced the hydrogen storage, specific capacitance, antibacterial and anticancer activities of the composite.

用于储氢、电化学、抗菌和抗癌的 WO3-GO 纳米复合材料的合成与表征

采用沉淀法、改良悍马法和超声法分别成功合成了三氧化钨纳米颗粒（WO3 NPs）、氧化石墨烯纳米片（GO NSs）和 WO3-GO （50 毫克和 100 毫克）纳米复合材料（NCs）。利用各种表征技术确认了单个材料和复合材料的形成。研究了合成材料的储氢、电化学、抗菌和抗癌性能。X射线衍射、拉曼和 XPS 分析证实了复合材料的形成。利用 BET 分析法研究了 WO3 NPs 和 WO3-GO NC 的表面积和孔径分布。发现 WO3-GO 50 mg 和 WO3-GO100 mg NCs 的储氢能力分别为 1.05 和 2.08 wt%。XRD、拉曼、元素和 TG 分析被用来研究氢的吸附和解吸。与 WO3 NPs 相比，WO3-GO NCs 显示出更高的比电容。研究还考察了 WO3 NPs 和 WO3-GO NC 对大肠杆菌和金黄色葡萄球菌的抗菌活性以及对人类乳腺癌细胞的抗癌效果。研究结果表明，GO 的加入增强了复合材料的储氢、比电容、抗菌和抗癌活性。
