“…Zeolitic imidazolate framework-8 (ZIF-8) is a Znbased MOF that has a very huge specific surface area, at 1123 m 2 /g. 117 For instance, Zr-based UiO-67 displays an extremely high Brunauer−Emmett−Teller (BET) specific surface area of 2500 m 2 /g, 118 as compared to its oxide counterpart (ZrO 2 ) with a specific surface area of only 44.8 m 2 /g. 119 Moreover, the porous structure of the MOF is a very attractive characteristic.…”

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 .

“…A series of zirconium-based metal-organic gels have been studied, which consist of Zr-MOF nanoparticles, including UiO-66, NH 2 -UiO-66, UiO-67, MOF-801 and MOF-808, etc. [26][27][28][29][30][31][32][33] Through the MOG route, the synthesis of Zr-MOF nanoparticles is simple and rapid under mild conditions. 33,34 For example, due to the presence of MOF nanoparticles in the gel matrix, the improved performance for adsorption and conversion of CO 2 was observed for UiO-66-NH 2 gel.…”

“…[42] Because of the special microstructures, photonic crystals can be introduced into photoanode with higher light-harvesting efficiency. [43][44][45] Conceivably, butterfly wings are capable of maintaining the separated state of photo-generated charge, subsequently used for chemical conversion. [46] Additionally biomimetic artificial photonic crystals provide a general strategy for replicating chitin-based structures with fine hierarchical 3D morphology, and enable the conversion of sophisticated natural 3D bio-organic structures into various composites with optical, electronic or catalytic application.…”

A series of Zr-based metal-organic framework (Zr-MOF) films are anchored on the surface of butterfly wing via solvothermal method for HER application, including UiO-66, NH 2-UiO-66 and UiO-67. Oriented nanoparticles are anchored on the photonic crystal bio-template. The distinctive design of the Zr-MOFs/B composites enables remarkable photoelectrocatalytic HER activity in comparison with corresponding intrinsic Zr-MOFs, primarily due to the synergy effect between MOFs and the photonic crystal. The cathode current increases to 1.94, 0.98 and 3.64 mA cm À 2 for UiO-66/B, NH 2-UiO-66/B and UiO-67/B, respectively, at an overpotential of À 0.6 V vs RHE when irradiated for 30 min upon simulated sunlight. Upon simulated sunlight irradiation, the carrier density increases by 2.00, 1.26 and 1.48 times for UiO-66/B, NH 2-UiO-66/B and UiO-67/B, respectively. This work paves a promising pathway for designing efficient HER electrocatalysts by combination of Zr-MOFs and photo-active butterfly wings.
