“…The ultrahigh CO selectivity is attributed to the enrichment of CO 2 molecules, which suppress the H 2 O reduction. The promising photocatalytic CO 2 reduction reaction is that CO 2 obtains photogenerated electrons, ,− and the hydrogen protons produced by H 2 O splitting are reduced to the required hydrocarbons. Thermodynamically, the reduction of H 2 O is more likely to occur than the reduction of CO 2 to hydrocarbons.…”

Photocatalytic reduction of CO 2 to value-added chemicals is known to be a promising approach for CO 2 conversion. The design and preparation of ideal photocatalysts for CO 2 conversion are of pivotal significance for the sustainable development of the whole society. In this work, we integrated two functional organic linkers to prepare a novel metal organic framework (MOF) photocatalyst {[Co(9,10-bis(4-pyridyl)anthracene) 0.5 (bpda)]•4DMF} (Co-MOF). The existence of anthryl and amino groups leads to a wide range of visible light absorption and efficient separation of photogenerated electrons. To extend the lifetime of photogenerated electrons in the photocatalytic system, we modified Co-MOF particles onto g-C 3 N 4 . As expected, Co-MOF/g-C 3 N 4 composites exhibited an ultrahigh selectivity (more than 97%) in the photocatalytic process, and the highest CO production rate (1824 μmol/g/h) was 7.1 and 27.2 times of Co-MOFs and g-C 3 N 4 , respectively. What's more, we also discussed the reaction mechanism of the Co-MOF/g-C 3 N 4 photocatalytic CO 2 reduction, and this work paves the pathway for designing photocatalysts with ideal CO 2 reduction performance.

“…108 Similarly, doping of Co into Ni-MOF resulted in the highest charge separation efficiency for Co 0.1 Ni 0.9 -MOF, which was attributed to the magnetoelectric coupling due to the doping of a certain amount of Co as well as the polarized nature of Ni(DPA) 2 . 109 The Co-MOF mentioned above showed strong nucleophilicity and high reactivity to CO 2 . In addition, the Counsaturated metal sites enhance the affinity of CO 2 .…”

The conversion of CO2 into commercially available chemical fuels is a meaningful strategy for mitigating the greenhouse effect. Photocatalytic CO2 reduction is an attractive strategy due to its clean and environmentally friendly properties, and seeking efficient photocatalysts is crucial to accomplish high yield and selectivity of CO2. Metal–organic frameworks (MOFs) are favorable for photocatalytic reactions due to their high specific surface areas and abundant active sites. To facilitate the search for practical, green, and sustainable MOF photocatalysts, this paper summarizes the effects of different preparation processes on the photoresponsiveness and pore structure of MOFs, and describes the challenges of large-scale industrial production in the future. Moreover, the mechanism of MOFs photocatalytic reduction of CO2 and the factors affecting the photocatalytic performance were summarized in detail. Based on this, this review focuses on the design of band structure, construction of heterojunction, and design of goal-oriented MOF morphology to propose modification strategies and point out the key to improving photocatalytic performance. Finally, the challenges and application prospects of MOFs in photocatalytic reduction of CO2 are further discussed.

The inherent challenges in using metal‐organic frameworks (MOFs) for photocatalytic CO2 reduction are the combination of wide‐range light harvesting, efficient charge separation and transfer as well as highly exposed catalytic active sites for CO2 activation and reduction. We present here a promising solution to satisfy these requirements together by modulating the crystal facet and surface atomic structure of a porphyrin‐based bismuth‐MOF (Bi‐PMOF). The series of structural and photo‐electronic characterizations together with photocatalytic CO2 reduction experiment collectively establish that the enriched Bi active sites on the (010) surface prefer to promote efficient charge separation and transfer as well as the activation and reduction of CO2. Specifically, the Bi‐PMOFs‐120‐F with enriched surface Bi active sites exhibits optimum photocatalytic CO2 reduction performance to CO (28.61 umol·h‐1g‐1) and CH4 (8.81 umol·h‐1g‐1). This work provides new insights to synthesize highly efficient main group p‐block metal Bi‐MOF photocatalysts for CO2 reduction through a facet‐regulation strategy and sheds light on the surface structure‐activity relationships of the MOFs.
