Graphene quantum dots (GQDs) have aroused great interest in the scientific community in recent years due to their unique physicochemical properties and potential applications in different fields. To date, much research has been conducted on the ingenious design and rational construction of GQDs‐based nanomaterials used as electrode materials and/or electrocatalysts. Despite these efforts, research on the efficient synthesis and application of GQDs‐based nanomaterials is still in the early stages of development and timely updates of recent research progress on new design concepts, synthetic strategies, and significant breakthroughs in GQDs‐based nanomaterials are highly desired. In light of the above, the effect of synthetic methods on the final product of the GQDs, the GQDs synthesis mechanism, and specific perspectives regarding the effect of the unique surface and structural properties of GQDs (e.g., defects, heteroatom doping, surface/edge state, size, conductivity) on the electrochemical energy‐related systems are discussed in‐depth in this review. Additionally, this review also focuses on the design of GQDs‐based composites and their applications in the fields of electrochemical energy storage (e.g., supercapacitors and batteries) and electrocatalysis (e.g., fuel cell, water splitting, CO₂ reduction), along with constructive suggestions for addressing the remaining challenges in the field.

石墨烯量子点基高级电极材料：设计，合成及其在电化学储能和电催化中的应用

近年来，石墨烯量子点（GQD）由于其独特的理化特性和在不同领域的潜在应用而引起了科学界的极大兴趣。迄今为止，已经对基于GQDs的纳米材料用作电极材料和/或电催化剂的巧妙设计和合理构造进行了大量研究。尽管做出了这些努力，基于GQDs的纳米材料的有效合成和应用的研究仍处于发展的早期阶段，并且人们迫切需要对基于GQDs的纳米材料的新设计概念，合成策略和重大突破的最新研究进展进行及时更新。。鉴于上述情况，合成方法对GQD最终产品，GQD合成机理的影响，本综述深入讨论了有关GQD独特的表面和结构特性（例如，缺陷，杂原子掺杂，表面/边缘状态，尺寸，电导率）对电化学能量相关系统的影响的具体观点。此外，本文还将重点介绍基于GQD的复合材料的设计及其在电化学储能（例如，超级电容器和电池）和电催化（例如，燃料电池，水分解，CO₂还原），以及针对该领域剩余挑战的建设性建议。
