Covalent Organic Frameworks for the Oxygen Reduction Reaction: Designing Strategies

Abstract

Covalent organic frameworks (COFs) are an emerging crystalline polymer that is constructed by the organic blocks through reversible polymerization. In this review, we have summarized the strategies for designing covalent organic frameworks for the oxygen reduction reaction. The discussion involved the new structural design of COFs and modifications fitting to the applications. Active sites manipulated scale from the single atom‘s electron states to the body framework arrangements. This review has anticipated the researchers to enlighten new ORR catalyst designing and optimization.
