“…Combination of both materials in the form of Al@MIL‐53(Al) core–shell NPs produced a higher CO yield than that obtained from bare Al NPs under laser irradiation (Figure 7B). High selectivity toward CO 2 hydrogenation under light‐heat dual activation was also achieved using plasmonic MOF catalysts comprising multiple Au@Pd core–shell NPs encapsulated within an UiO‐66‐NH 2 (Zr 6 O 4 (OH) 4 (BDC‐NH 2 ) 6 , BDC‐NH 2 = 2‐amino‐1,4‐benzenedicarboxylic acid) matrix 141 . It was proposed that the multiple Au NP cores acted as a plasmonic nanoantenna generating hot‐electrons, while the thin Pd coating (<1 nm) further improved CO 2 reduction by a decrease of the HOMO‐LUMO gap and the reaction energy barrier of CO 2 * to COOH*.…”

Plasmonic metal‐organic frameworks are composite nanoparticles comprising plasmonic metal nanoparticles (NPs) embedded within a metal‐organic framework (MOF) matrix. As a result, not only the functionalities of the individual components are retained, but synergistic effects additionally provide improved chemical and physical properties. Recent progress in plasmonic MOFs has demonstrated the potential for nanofabrication and various nanotechnology applications. Synthetic challenges toward plasmonic MOFs have been recently addressed, resulting in new opportunities toward practical applications, such as surface‐enhanced Raman scattering, therapy, and catalysis. The impact of key parameters (thermodynamic vs. kinetic) on the synthetic pathways of plasmonic MOFs is reviewed, while providing insight into related progress toward structure‐derived applications.

Because of the increasing energy demand of the growing human population, the world is facing a crisis of depleting fossil fuels as well as huge amounts of CO 2 emissions being put into the environment. Therefore, to combat these two major issues, catalytic CO 2 hydrogenation is introduced which utilizes the abundant CO 2 in the atmosphere and at the same time generates clean fuel and chemicals. Metal organic frameworks (MOFs) are a very attractive catalyst for the conversion of CO 2 into CH 4 due to their high surface area, tunable chemical composition, high porosity, and well-ordered structures. They are also photoresponsive materials. This review discusses the various strategies and modifications implemented to further ameliorate the thermal, photo-, and photothermal catalytic performance of MOFs. Initially, three main catalytic approaches, namely thermal catalysis, photocatalysis, and photothermal catalysis, are thoroughly discussed to understand the mechanism and the differences between them with their characteristics and limitations. Then, a comprehensive review was carried out on various strategies employed to augment the performance of MOFs for CO 2 methanation, such as metal addition and incorporation, MOF templating, surface sensitization, formation of heterojunctions, and organic linker modifications via functionalization. Comparisons between MOF-based catalyst and traditional catalyst were carried out to elucidate the beneficial properties of MOFs toward CO 2 methanation. The selectivity control for CH 4 production was then extensively reviewed in terms of operating parameters, type of catalyst, and reactor. Finally, the mechanism, pathways, intermediates, and adsorbed species involved for CO 2 methanation are thoroughly discussed with the help of diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) analysis and Density Functional Theory (DFT) calculations. Therefore, it is clear that metal organic frameworks are highly promising porous crystalline materials for CO 2 methanation reaction and have countless possibilities for further enhancement and development to maximize the production of renewable CH 4 .

“…However, the pure UiO-66 usually demonstrates a fast recombination rate of electron holes and poor photocatalytic CO 2 reduction activity ( Peng et al, 2020 ). Recently, some tactics, such as replacing the original ligands ( Zhang et al, 2021 ), depositing precious metals or other co-catalysts on the surface ( Zhang et al, 2020 ), and doping other metal elements to form new coordination bonds ( Yang et al, 2017 ) have been investigated to ameliorate the performance of UiO-66. Coupling UiO-66 with another photocatalytic semiconductor to construct a heterostructure composite can adjust the electronic transfer path and achieve high separation efficiency of photogenerated charges, which has been deemed as one of the most promising procedures to elevate the photocatalytic performance ( Su et al, 2017 ).…”

One of the basic challenges of CO2 photoreduction is to develop efficient photocatalysts, and the construction of heterostructure photocatalysts with intimate interfaces is an effective strategy to enhance interfacial charge transfer for realizing high photocatalytic activity. Herein, a novel UiO-66/Bi4O5Br2 heterostructure photocatalyst was constructed by depositing UiO-66 nanoparticles with octahedral morphology over the Bi4O5Br2 nanoflowers assembled from the Bi4O5Br2 nanosheets via an electrostatic self-assembly method. A tight contact interface and a built-in electric field were formed between the UiO-66 and the Bi4O5Br2, which was conducive to the photo-electrons transfer from the Bi4O5Br2 to the UiO-66 and the formation of a type-II heterojunction with highly efficient charge separation. As a result, the UiO-66/Bi4O5Br2 exhibited improved photocatalytic CO2 reduction performance with a CO generation rate of 8.35 μmol h−1 g−1 without using any sacrificial agents or noble co-catalysts. This work illustrates an applicable tactic to develop potent photocatalysts for clean energy conversion.
