Abstract
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 •
