“…We attached two photocatalytic centers Re I (bpy)(CO) 3 X and [Ir III (bpy)Cp*OH] + on a 2D MOL (Zr-TCBPE-MOL, TCBPE = tetrabenzoatetraphenylethylene) that can only transfer energy to the active centers ( Figure 6 b). 129 The light-harvesting effect of the MOL enhanced catalytic activity by 6 times for the Re center to produce CO and 110 times for the Ir center to produce HCO 2 H as compared to homogeneous controls without energy transfer. We must note that 1e – transfer photocatalysis that involves radical reaction, in principle, does not benefit from this energy transfer scheme.…”

Metal–organic layers (MOLs) are two-dimensional analogues of metal–organic frameworks (MOFs) with a high aspect ratio and thickness down to a monolayer. Active sites on MOLs are more accessible than those on MOFs thanks to the two-dimensional feature of MOLs, which allows easier chemical modification around the catalytic center. MOLs can also be assembled with other functional materials through surface anchoring sites that can facilitate charge/energy transport through the hybrid material. MOLs are thus quite suitable for interfacial catalysis like electrocatalysis and photocatalysis. In this outlook, we focus on representative progress of constructing unique interfacial sites on MOLs with designer paths for charge separation and energy transfer, as well as cooperative cavities for superior substrate adsorption and activation. We also discuss challenges and potentials in the future development of MOL catalysts and catalysts beyond MOLs.

“…With the excessive consumption of fossil fuels, the amount of CO 2 in the atmosphere is increasing rapidly, causing the greenhouse effect to seriously threaten human′s living environment. Artificial photosynthesis of photocatalytic CO 2 reduction, not only can effectively reduce the amount of CO 2 , but also can obtain organic fuels or chemicals (CO, HCHO, CH 3 OH and CH 4 ), is a win‐win strategy and therefore favored by researchers . Therefore, to explore the basic physical and chemical issues of photocatalytic CO 2 reduction and design strategy for high‐efficiency photocatalytic materials is the main ways to improve the CO 2 conversion efficiency.…”

The search for highly active photocatalysts remains one of the most challenging tasks for realizing efficient solar energy utilization. Inspired by their unique and excellent physicochemical properties, ultrathin two-dimensional (2D) semiconductors present great advantages in photocatalytic researches. In this review, we summarize the state-of-art progress on the ultrathin 2D semiconductors with a particular emphasis on their recent advances in energy and environment applications. First, we introduce the historical developments of 2D nanomaterials, and outline their advantages in terms of photocatalysis. Second, the classifications of ultrathin 2D semiconductors are summarized based on their structure and compositions. Further, various energy and environment applications including water splitting, CO 2 reduction, N 2 fixation, organic syntheses, NO x removal, water treatment, and sterilization in recent years (mainly in the recent 3 years) are highlighted in detail. Finally, the personal perspectives on future challenges and outlooks in the field of energy and environment applications are featured.[a] Dr.

“…Using this material in combination with Zr-based MOFs for photocatalytic CO 2 conversion would result in better energy collection and utilization, thereby boosting photocatalytic conversion. In 2019, Hu et al developed 2D light-harvesting MOF analogs [i.e., metal-organic-layer (MOL)], which were efficient multiple photo-exciton injectors in short duration and transport to Re-and Ir-based reaction metal site for photocatalytic reduction of CO 2 to CO and/or HCOOH [184]. Therefore, the incorporation of MOLs catalytic antenna enhances the directional multi-photon-generated electron injection and improves transport to the reductive site of the MOF catalytic center (Re-and Ir-based), affecting prohibited charge recombination to increase the photocatalytic performance of the respective conjugated MOFs.…”

The accumulation of carbon dioxide (CO2) pollutants in the atmosphere begets global warming, forcing us to face tangible catastrophes worldwide. Environmental affability, affordability, and efficient CO2 metamorphotic capacity are critical factors for photocatalysts; metal-organic frameworks (MOFs) are one of the best candidates. MOFs, as hybrid organic ligand and inorganic nodal metal with tailorable morphological texture and adaptable electronic structure, are contemporary artificial photocatalysts. The semiconducting nature and porous topology of MOFs, respectively, assists with photogenerated multi-exciton injection and adsorption of substrate proximate to void cavities, thereby converting CO2. The vitality of the employment of MOFs in CO2 photolytic reaction has emerged from the fact that they are not only an inherently eco-friendly weapon for pollutant extermination, but also a potential tool for alleviating foreseeable fuel crises. The excellent synergistic interaction between the central metal and organic linker allows decisive implementation for the design, integration, and application of the catalytic bundle. In this review, we presented recent MOF headway focusing on reports of the last three years, exhaustively categorized based on central metal-type, and novel discussion, from material preparation to photocatalytic, simulated performance recordings of respective as-synthesized materials. The selective CO2 reduction capacities into syngas or formate of standalone or composite MOFs with definite photocatalytic reaction conditions was considered and compared.
