Graphene has shown great potential in various application fields due to its excellent carrier transportation, ultra-high specific surface area, good mechanical properties, and light transmittance. However, pure graphene still exhibits some insurmountable defects, such as difficulty in simple and large-scale preparation, and limitations in application. The electrochemical method is a simple, clean, and environmentally friendly method. The rapid and simple preparation of graphene and its derivatives by electrochemical methods has important environmental significance. Moreover, rGO-based nanohybrids can be prepared by convenient and quick electrodeposition or cyclic voltammetry (CV), or to change the morphology and structure of graphene and its derivatives to achieve the purpose of improving material properties. This work mainly summarizes electrochemically related graphene from four aspects: (i) the method of electrochemical exfoliation of graphene; (ii) types of electrodeposition rGO-based nanohybrids; (iii) electrochemical regulation of the structure of rGO-based mixtures; (iv) environmental applications of rGO-based nanohybrids prepared by electrodeposition. This article critically discusses the advantages and disadvantages of electrochemical-related graphene, outlines future challenges, and provides insightful views and references for other researchers.
石墨烯因其优异的载流子输运、超高的比表面积、良好的机械性能和透光率，在各个应用领域表现出了巨大的潜力。然而，纯石墨烯仍然存在一些难以克服的缺陷，例如制备方法简单且规模大、应用受限等问题。电化学方法是一种简单、清洁、环保的方法。通过电化学方法快速、简单地制备石墨烯及其衍生物具有重要的环境意义。此外，通过方便快捷的电沉积或循环伏安法（CV）可以制备基于 rGO 的纳米杂化物，或者改变石墨烯及其衍生物的形态和结构，以达到改善材料性能的目的。本工作主要从四个方面综述了与电化学相关的石墨烯：（i）石墨烯的电化学剥离方法；（ii）基于电沉积的 rGO 纳米杂化物的类型；（iii）rGO 基混合物结构的电化学调控；（iv）电沉积制备的 rGO 基纳米杂化物的环境应用。本文批判性地讨论了与电化学相关的石墨烯的优缺点，概述了未来的挑战，并为其他研究人员提供了有见地的观点和参考。
