摘要

由于其独特的结构和电子特性,石墨烯纳米带(GNR)已成为催化氧还原反应(ORR)的理想候选材料。本综述全面概述了将 GNR 用作 ORR 应用催化剂或支撑材料的最新进展,并讨论了其基本活性位点、合成策略和优化方法。GNR 与掺杂剂、杂原子取代以及与其他材料杂化之间的协同效应也包括在内。此外,实验研究还阐明了 GNR 结构与 ORR 动力学之间错综复杂的相互作用,为催化剂的设计和优化提供了宝贵的见解。本综述强调了基于 GNR 的催化剂在 ORR 电催化方面的潜力,并强调了为克服现有限制以实现其在未来电化学能源转换技术中的适用性而正在进行的努力。

Recent progress on graphene nanoribbon-based electrocatalysts for oxygen reduction reaction

Graphene nanoribbons (GNRs) have emerged as promising candidates for catalysing the oxygen reduction reaction (ORR) due to their unique structural and electronic properties. This review presents a comprehensive overview of recent advances in utilising GNRs as catalysts or support materials for ORR application and discusses the underlying active sites, synthesis strategies, and optimisation approaches. The synergistic effects between GNRs and dopants, heteroatom substitutions and hybridisation with other materials have also been included. Moreover, experimental studies have elucidated the intricate interplay between GNR structure and the ORR kinetics, providing valuable catalyst design and optimisation insights. This review highlights the potential of GNR-based catalysts for ORR electrocatalysis and underscores the ongoing efforts to overcome existing limitations to realise their applicability in future electrochemical energy conversion technologies.

期刊介绍: The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
