Abstract
Developing high-performance, durable, yet low-lost catalysts for electrocatalytic
water splitting technology has been a research priority to tackle the global energy
crisis. In this regard, covalent organic frameworks (COFs) have received great attention
as promising water splitting electrocatalysts as they can provide an excellent platform
for the settlement of electrocatalytic active site, high porosity, and good stability.
In this review, recent advances on the design and application of COFs for water electrolysis,
which are hydrogen and oxygen evolution reaction electrocatalysts, are briefly discussed.
Among them, both noble and non-noble metals containing COFs as well as metal-free
COF-based electrocatalysts are elaborated. Furthermore, a brief outlook on the development
of COFs in the field of water splitting electrocatalysis is provided.
