Engineering Covalent Organic Frameworks for Light-Driven Hydrogen Production from Water

Production of sustainable and renewable energy is a subject of global importance and is a challenging goal in the fields of chemistry and materials science. This Perspective focuses on the use of two sustainable resources on this planet, that is, water and sunlight, for the production of green chemical energy—hydrogen. Special interest is directed to the recent progress in engineering covalent organic framework systems that allow the construction of tailor-made semiconducting structures to produce hydrogen from water upon irradiation. We scrutinized the structure design concept and synthetic strategy with an aim to disclose a full picture of photo-to-chemical energy conversion.
