Recent Advances of Covalent Organic Frameworks as Water Splitting Electrocatalysts

Developing high performance, durable, yet low-lost catalyst 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 numerous attentions as promising water splitting electrocatalysts as they can provide an excellent platform for settlement of electrocatalytic active site, high porosity, and good stability. In this review, recent advance on the design and application of COFs for water electrolysis, that are hydrogen and oxygen evolution reaction (HER and OER) electrocatalysts are briefly discussed. Among them, both noble and non-noble metals containing COFs as well as metal-free COFs based electrocatalysts are elaborated. Furthermore, a brief perspective on development of COFs in the field of water splitting electrocatalysis is provided.
