Abstract

Materials degradation is a major factor that limits the wider adoption of renewable and clean energy technologies. This is particularly true for the Pt group metal-free (PGM-free) atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts. While many experimental studies have investigated and reported the phenomenological aspects of M-N-C degradation, only a few modeling studies have considered degradation mechanisms at the atomic level. Understanding the mechanisms responsible for activity loss occurring in atomically dispersed M-N-C’s is crucial towards rationally designing active, durable, and less expensive Earth-abundant catalysts. Towards this end, we have surveyed recent literature concerning the modeling of corrosion mechanisms that impact M-N-C catalysts (Fe–N–C, in particular) and offer our own perspectives on the future direction of this field.

原子分散的 Fe-N-C 电催化剂中氧还原活性损失机制建模
材料降解是限制可再生能源和清洁能源技术广泛应用的一个主要因素。对于铂族无金属(PGM-free)原子分散金属-氮-碳(M-N-C)催化剂来说尤其如此。虽然许多实验研究已经调查并报告了 M-N-C 降解的现象,但只有少数建模研究考虑了原子层面的降解机制。了解原子分散的 M-N-C 中发生活性损失的机理,对于合理设计活性、耐久性和低成本的地球富集催化剂至关重要。为此,我们对近期有关影响 M-N-C 催化剂(尤其是 Fe-N-C)腐蚀机制建模的文献进行了调查,并对该领域的未来发展方向提出了自己的看法。

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 •
