Abstract

In this paper, the authors have report the fabrication of MnS 2 with reduced graphene oxide (MnS 2 -RGO) composite through co-precipitation route. The prepared samples were characterized by analytical instruments like XPS, FTIR, XRD, BET, SEM-EDX, TEM, UV-DRS and TGA for understanding the optical, electrochemical, structural and thermal properties. The prepared composites and bare MnS 2 were examined for their photocatalytic performance by the degradation of o -nitrophenols under visible light irradiations. However, MnS 2 -RGO-2 composite was the most effective photocatalyst for the degradation of o -nitrophenols in 75 min and can be recycled for continuous five cycles. The MnS 2 -RGO composites and bare MnS 2 were further examined their antimicrobial activity over E.coli, S.aureus, S.typhi and V.cholera . In addition, the effect of RGO on enhanced catalytic degradation of o -nitrophenols under visible light irradiations and antibacterial activity as prepared composite exhibits tremendous properties of both MnS 2 and RGO.

Mns2和还原氧化石墨烯共沉淀介导的复合材料对邻硝基苯酚和病原体失活的潜在影响
本文报道了用共沉淀法制备还原性氧化石墨烯(MnS 2 -RGO)复合材料的方法。利用XPS、FTIR、XRD、BET、SEM-EDX、TEM、UV-DRS和TGA等分析仪器对制备的样品进行表征,了解其光学、电化学、结构和热性能。在可见光照射下,考察了制备的复合材料和裸mns2对邻硝基酚的光催化性能。而mns2 -RGO-2复合光催化剂在75 min内对邻硝基苯酚的降解效果最好,可连续循环5次。进一步研究了MnS 2 -RGO复合物和裸MnS 2对大肠杆菌、金黄色葡萄球菌、伤寒沙门氏菌和霍乱弧菌的抑菌活性。此外,RGO在可见光照射下对o -硝基酚的催化降解和抗菌活性的增强作用表明,制备的复合材料具有mns2和RGO的双重特性。
