Abstract

Due to the sluggish nature of the oxygen reduction reaction (ORR), it requires electro-catalysts to speed up the kinetics of ORR at a practical level. Covalent organic frameworks (COFs)-based materials were reported to be one of the most promising electrocatalysts for ORR among the different low-cost ORR electrocatalysts. These molecular COFs-materials offer the following benefits: (i) precise control of active sites, (ii) simple understanding of structure-activity relationships, (iii) chemically adjustable and well-defined pore size architecture, and (iv) adheres to well-defined reaction pathways. Surprisingly, the importance of structure-activity correlations is well understood, and a number of strategies for improving the activity of such catalysts have been documented. The goal of this study is to simplify COFs chemistry, highlight recent comprehensive designs for ORR, and highlight some future features of COFs engineering for ORR electrocatalysis.

氧还原反应用共价有机骨架纳米复合材料
由于氧还原反应(ORR)的缓慢性质,在实际水平上需要电催化剂加速ORR的动力学。在各种低成本的ORR电催化剂中,以共价有机框架(COFs)为基础的材料是最有前途的ORR电催化剂之一。这些分子cofs材料具有以下优点:(i)对活性位点的精确控制,(ii)对结构-活性关系的简单理解,(iii)化学上可调节且定义明确的孔径结构,以及(iv)遵循明确的反应途径。令人惊讶的是,结构-活性相关性的重要性得到了很好的理解,并且已经记录了许多提高这类催化剂活性的策略。本研究的目的是简化COFs的化学反应,重点介绍ORR的最新综合设计,以及未来用于ORR电催化的COFs工程的一些特点。

期刊介绍: The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
