Abstract

Recent advances in clean technologies have led to the development of environmentally sustainable methods for synthesizing reduced graphene oxide (rGO), a material crucial for several applications. This review explores various eco-friendly approaches, such as electrochemical, photochemical, photothermal, laser, and hydrothermal reduction, along with the innovative spun calcination method. Unlike conventional methods, which often use toxic chemicals and require high energy, these green methods reduce environmental impact while enhancing scalability and material properties. We particularly highlight the spun calcination method, which employs electrospinning, for its ability to produce high-purity rGO with minimal defects and waste. We also discuss the optimization of rGO synthesis through the use of different polymer precursors such as polyacrylonitrile (PAN) and polyvinyldene fluoride (PVDF). This review aims to guide future research toward more efficient, scalable, and sustainable rGO production, supporting broader advancements in green nanotechnology.

rGO 合成的环境可持续技术：聚焦纺丝煅烧和清洁技术进步

清洁技术的最新进展促使人们开发出了具有环境可持续性的还原氧化石墨烯（rGO）合成方法，这种材料在多种应用中至关重要。本综述探讨了各种生态友好型方法，如电化学、光化学、光热、激光和水热还原法，以及创新的纺丝煅烧法。传统方法通常使用有毒化学物质并需要高能量，与之不同的是，这些绿色方法可减少对环境的影响，同时提高可扩展性和材料性能。我们特别强调了采用电纺丝技术的纺丝煅烧法，因为这种方法能够生产出高纯度的 rGO，而且缺陷和废料极少。我们还讨论了通过使用不同的聚合物前体（如聚丙烯腈（PAN）和聚偏二氟乙烯（PVDF））来优化 rGO 合成的问题。本综述旨在指导未来的研究，以实现更高效、可扩展和可持续的 rGO 生产，支持绿色纳米技术的更广泛进步。
