“…The CO yield of cuboidal Zn-MOF-NH 2 was only 0.047 μmol•h −1 , while 2D Zn-MOF-NH 2 was up to 0.28 μmol• h −1 , which suggests that the 2D structure can shorten the transport distance of electrons. 172 The photocatalysts have been synthesized through 2D ultrathin MOF nanosheets (2.4 ± 0.5 nm) coordinated with Co single atoms (named as Co-MNSs) using the bottom-up synthetic strategy. The key to the synthesis of 2D MOFs is using polyvinylpyrrolidone as the surfactant, which can limit the anisotropic growth and avoid the generation of cuboidal MOFs (Figure 10c).…”

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.

“…[55] Compared with bulk MOF materials, ultrathin 2D MOF materials with a high aspect ratio exhibit shortened carrier migration distance, abundant surface reaction sites, adjustable band gap, and higher light-trapping capacity. [56,57] Additionally, the high surface area of 2D MOFs facilitates not only substrate or product diffusion but also binding with other auxiliary catalysts, [58] making 2D MOF nanosheets highly promising for photocatalysis. For instance, using porous Ni foam as both a substrate and a self-sacrificial template, Ding Reproduced with permission.…”

Photocatalytic membranes can effectively integrate membrane separation and photocatalytic degradation processes to provide an eco‐friendly solution for efficient water purification. It is of great significance to develop highly efficient photocatalytic membranes driven by visible light to ensure the long‐term stability of membrane separation systems and the maximum utilization of solar energy. Metal‐organic framework (MOF) is an emerging photocatalyst with a well‐defined structure and tunable chemical properties, showing a broad application prospect in the construction of high‐performance photocatalytic membranes. Herein, this work provides a comprehensive review of recent advancements in MOF‐based photocatalytic membranes. Initially, this work outlines the main tailoring strategies that facilitate the enhancement of the photocatalytic activity of MOF‐based photocatalysts. Next, this work introduces commonly used methods for fabricating MOF‐based photocatalytic membranes. Subsequently, this work discusses the application and mechanisms of MOF‐based photocatalytic membranes toward organic pollutant degradation, metal ion removal, and membrane fouling mitigation. Finally, challenges in developing MOF‐based photocatalytic membranes and their practical applications are presented, while also pointing out future research directions toward overcoming these existing limitations.

“…prepared a series of 2D ZnMOF‐NH 2 /Cu composite photocatalysts with different mass ratios by in situ photo‐deposition method. [ 35 ] Under the same conditions, the CO formation rate of the composite photocatalyst doped with 1 wt% copper ion is the highest, which is 0.76 µmol h −1 . The characterization of ZnMOF‐NH 2 /Cu photocatalyst shows that the thickness of ZnMOF‐NH 2 /Cu is only 14 nm, and ZnMOF‐NH 2 /Cu has the largest BET surface area, the highest photocurrent response intensity, the smaller arc radius and the weaker PL intensity.…”

Artificial photosynthesis can convert carbon dioxide into high value‐added chemicals. However, due to the poor charge separation efficiency and CO2 activation ability, the conversion efficiency of photocatalytic CO2 reduction is greatly restricted. Ultrathin 2D photocatalyst emerges as an alternative to realize the higher CO2 reduction performance. In this review, the basic principle of CO2 photoreduction is introduced, and the types, advantages, and advances of 2D photocatalysts are reviewed in detail including metal oxides, metal chalcogenides, bismuth‐based materials, MXene, metal‐organic framework, and metal‐free materials. Subsequently, the tactics for improving the performance of 2D photocatalysts are introduced in detail via the surface atomic configuration and electronic state tuning such as component tuning, crystal facet control, defect engineering, element doping, cocatalyst modification, polarization, and strain engineering. Finally, the concluding remarks and future development of 2D photocatalysts in CO2 reduction are prospected.
