Abstract

To address the inherent low conductivity of MoS₂, we developed a novel, simple, green, and scalable method for the preparation of graphene/MoS₂ composites using a laboratory-designed system. Through systematic optimization, the optimal preparation conditions were determined. Moreover, this method differs from traditional approaches that require high temperatures or hazardous reagents by enabling simultaneous exfoliation and compositing under mild conditions. Thus offering significant environmental and practical advantages. Comprehensive structural characterizations were conducted using XRD, Raman, SEM, TEM, HRTEM, and XPS. The results confirmed that bulk MoS₂ and graphite were successfully exfoliated into few-layer MoS₂ and graphene, respectively, which were subsequently composited to form a stable graphene/MoS₂ composite. The resulting material shows significantly enhanced electrical conductivity and charge transport, attributed to microstructure optimization and interfacial synergy. Overall, this study provides a practical and environmentally friendly strategy for improving the electrical conductivity of MoS₂, with promising potential for scalable production.
一种新的绿色方法合成高导电石墨烯/MoS 2复合材料
为了解决MoS 2固有的低电导率问题,我们开发了一种新颖、简单、绿色、可扩展的方法,使用实验室设计的系统制备石墨烯/MoS 2复合材料。通过系统优化,确定了最佳制备条件。此外,该方法与需要高温或危险试剂的传统方法不同,它可以在温和条件下同时进行剥离和合成。因此具有显著的环保和实用优势。采用XRD、Raman、SEM、TEM、HRTEM、XPS等手段对材料进行了全面的结构表征。结果证实,大块的MoS 2和石墨分别被成功剥离成几层的MoS 2和石墨烯,随后被复合形成稳定的石墨烯/MoS 2复合材料。由于微观结构优化和界面协同作用,所得材料的电导率和电荷输运显著增强。总的来说,该研究为提高MoS 2的导电性提供了一种实用且环保的策略,具有大规模生产的潜力。
