Frontiers in Energy 2019, Volume 13, Issue 2,   Pages 221-250 doi: 10.1007/s11708-019-0629-8

Abstract: Metal-organic frameworks (MOFs) have attracted much attention because of their large surface areas, tunable structures, and potential applications in many areas. In recent years, MOFs have shown much promise in CO photoreduction. This review summarized recent research progresses in MOF-based photocatalysts for photocatalytic reduction of CO . Besides, it discussed strategies in rational design of MOF-based photocatalysts (functionalized pristine MOFs, MOF-photosensitizer, MOF- semiconductor, MOF-metal, and MOF-carbon materials composites) with enhanced performance on CO reduction. Moreover, it explored challenges and outlook on using MOF-based photocatalysts for CO reduction.
