Advancements in the in-situ growth of catalysts for water electrolysis: Substrate considerations, performance evaluations, and future perspectives
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.
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 •
