Abstract

In-situ growth of catalysts for water electrolysis has gained significant advancements recently, it involves cultivating active electrocatalysts on conductive substrates such as metal foams and carbon-based materials, the latter play a pivotal role in influencing the morphology and architecture of catalysts and offer enhanced conductivity, abundant active sites, and improved mass transport. Numerous studies have predominantly focused on evaluating specific catalyst materials within various classifications and their preparation methods, but without addressing roles of supports. This review focuses on substrate considerations, performance evaluations, and prospectives. It provides a deeper understanding of the various strategies employed for in-situ growth of electrocatalysts and emphasizes the importance of different conductive substrates with case studies on the factors that affect catalytic activity. Furthermore, the prospects and challenges towards practical applications under some challenging conditions are highlighted. This review provides valuable strategies for the further development of rational design of catalyst–substrate as an enabling electrode.

水电解催化剂原位生长的进展:基质考虑、性能评估和未来展望
水电解催化剂的原位生长最近取得了重大进展,它涉及在金属泡沫和碳基材料等导电基底上培养活性电催化剂,后者在影响催化剂的形态和结构方面起着关键作用,并具有更强的导电性、丰富的活性位点和更好的质量传输。大量研究主要集中于评估各种分类中的特定催化剂材料及其制备方法,但没有涉及支撑物的作用。本综述侧重于基质考虑、性能评估和前景展望。通过对影响催化活性的因素进行案例研究,本综述加深了对电催化剂原位生长所采用的各种策略的理解,并强调了不同导电基底的重要性。此外,还强调了在一些具有挑战性的条件下实际应用的前景和挑战。这篇综述为进一步合理设计催化剂基底作为使能电极提供了宝贵的策略。

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 •
