Photoreduction of CO into reusable carbon forms is considered as a promising approach to address the crisis of energy from fossil fuels and reduce excessive CO emission. Recently, metal-organic frameworks (MOFs) have attracted much attention as CO photoreduction-related catalysts, owing to their unique electronic band structures, excellent CO adsorption capacities, and tailorable light-absorption abilities. Recent advances on the design, synthesis, and CO reduction applications of MOF-based photocatalysts are discussed here, beginning with the introduction of the characteristics of high-efficiency photocatalysts and structural advantages of MOFs. The roles of MOFs in CO photoreduction systems as photocatalysts, photocatalytic hosts, and cocatalysts are analyzed. Detailed discussions focus on two constituents of pure MOFs (metal clusters such as Ti-O, Zr-O, and Fe-O clusters and functional organic linkers such as amino-modified, photosensitizer-functionalized, and electron-rich conjugated linkers) and three types of MOF-based composites (metal-MOF, semiconductor-MOF, and photosensitizer-MOF composites). The constituents, CO adsorption capacities, absorption edges, and photocatalytic activities of these photocatalysts are highlighted to provide fundamental guidance to rational design of efficient MOF-based photocatalyst materials for CO reduction. A perspective of future research directions, critical challenges to be met, and potential solutions in this research field concludes the discussion.

“…The visible‐light absorption of NNU‐37 should result primarily from anthracene‐based bipyridine BPEA as the other carboxylate linker, BPDA, does not absorb in the visible region. The absorption of NNU‐37 shifts towards lower energy as compared with BPEA, indicating the presence of ligand‐to‐metal charge transfer which is commonly observed for MOFs . The charge photogeneration in NNU‐37 was studied using transient photocurrent measurements.…”

A water‐stable mixed‐linker metal–organic framework (MOF) was rationally synthesized using a controllable pillared‐layer method. The prepared Co(II)–MOF shows wide‐range absorption in the visible light region due to the incorporation of highly conjugated anthracene‐based bipyridine ligand. Experiments suggest that the MOF is highly efficient for the photoreduction of toxic Cr(VI) ions in water under visible light. Important issues affecting photocatalytic performance, such as the influence of pH and the control of electron–hole separation by scavenger, were carefully examined. Beyond Cr(VI) ions, we also explored the photocatalytic degradation performance of the MOF using a persistent azo dye as a model substrate, where H2O2‐involved advanced oxidation process was applied. Control experiments suggest that the introduction of environmentally benign H2O2 significantly enhances the degradation performance due to the generation of reactive hydroxyl radicals. The study not only demonstrates the great feasibility of the preparation of a new MOF photocatalyst through a controllable pillared‐layer method, but also reveals that rational functionalization of ligand in the MOF is convenient for achieving desirable applications.

Excessive CO emission due to a large amount of fossil fuel utilization has become a widespread concern, which causes both environmental and energy problems. To solve these issues, electrocatalytic and photocatalytic reduction of CO to produce value-added chemicals have gained immense attention. Recently, metal-organic frameworks (MOFs) and their derived materials with high specific surface areas, controllable pore structures, and tunable chemical properties exhibit promising performance among the reported catalytic materials for CO conversion. This review describes the recent advances on the rational design and synthesis of MOF-based electrocatalysts and photocatalysts for CO reduction. The importance of the catalytic processes is highlighted, followed by systematic understanding of MOF-based catalysts for CO reduction through electrochemical and photochemical approaches. Special emphasis of this review is to introduce basic catalyst design strategies and synthesis methods as well as their resulting electrocatalysts and photocatalysts. One of the major goals is to elucidate the structures and properties that link to their catalytic activity, selectivity, and stability towards to CO reduction. We also outline the challenges in this research area and propose the potential strategies for the rational design and synthesis of high-performance catalysts.
