Design and architecture of metal organic frameworks for visible light enhanced hydrogen production

Design and architecture of metal organic frameworks for visible light enhanced hydrogen production
MOFs offers a potential platform for anchoring photosensitizers and catalytic moieties, encapsulating metal nanoparticles, and supporting the semiconductor to drive chemical H2 production reactions by taking the advantages of large surface area, permanent pores and tunable channels as well as tailorable physical and chemical functions. Recently, considerable attention has been paid to the application of MOFs in heterogeneous photocatalysis for H2 production. In this review, the latest progress of MOFs involved in the reaction of H2 production from water and visible-light-enhanced H2 releasing from hydrogen carriers were summarized. The successful methods to maximize photocatalytic activity of H2 production from water by introducing light sensitization and anchoring catalytic sites within MOFs, tuning the band gap of MOFs by modification of functional groups were also highlighted. Also the latest advances in heterogeneous organic dye-sensitized metal nanoparticle supported on MOFs for photocatalytic H2 production and visible light enhanced H2 production from H2 carriers were emphasize. In the end, a brief perspective to the challenges and new development directions in the development of highly active MOFs to achieve high photocatalytic activity in the H2 production is also discussed, which would be of great interest in the solar energy conversion.
