Covalent organic frameworks (COFs), newly developed materials, exhibit considerable promise in the field of catalysis. COFs exhibit captivating catalytic characteristics, including thermal and chemical stability, customizable porosities, and the ability to place active sites flexibly with tunable functions. To establish a connection between structure and activity, this paper provides a thorough justification of the planned creation of covalent organic frameworks for photocatalysis, encompassing H2 production, carbon dioxide reduction, pollutants reduction and transformation of organic substances. We have investigated the catalytic sites that are active within covalent organic frameworks, encompassing the metals, molecular catalysts, and catalyst with single atom (SACs); the reactive skeleton/linkages; and the reactive pendant groups. This exploration aims to establish the benefits of using COF‐based catalysts compared to traditional catalysts. Despite the new advantages, numerous difficulties have also been noted with regard to the future. The objective of this review is to make it easier to design COF‐based composite materials for practical uses.

The rise in global temperatures and environmental contamination resulting from traditional fossil fuel usage has prompted a search for alternative energy sources. Utilizing solar energy to drive the direct splitting of water for hydrogen production has emerged as a promising solution to these challenges. Covalent organic frameworks (COFs) are ordered, crystalline materials made up of organic molecules linked by covalent bonds, featuring permanent porosity and a wide range of structural topologies. COFs serve as suitable platforms for solar‐driven water splitting to produce hydrogen, as their building blocks can be tailored to possess adjustable band gaps, charge separation capabilities, porosity, wettability, and chemical stability. Here, the impact of the interface in the context of the photocatalytic reaction is focused and propose strategies to enhance the hydrogen production performance of COFs photocatalysis. In particular, how hybrid photocatalytic interfaces affect photocatalytic performance is focused.
