Covalent Organic Frameworks for Sunlight-driven Hydrogen Evolution

Abstract An energy crisis is presently encountered with a promising opportunity for the rise of hydrogen technology, while feasible production of hydrogen calls for sophisticated structural design of water-splitting photocatalysts in terms of light harvesting and photogenerated exciton separation. Tuning to these can be anticipated from reticular synthesis of a newly emerging porous crystalline materials, covalent organic frameworks (COFs). In this review, we highlight synthetic strategies to modulate the photocatalytic water splitting performance. Future investigations regarding mechanistic aspects of the photocatalytic process of COFs are also outlined.
