“…Metal organic frameworks (MOFs) are promising materials with many active sites, a high specific area, and great regular channel characteristics. − MOFs have been utilized for the past 10 years to generate photochemical and electrochemical energy, particularly for OER, and to store chemical hydrogen gaseous fuel. − Organic linkers and metal nodes make MOFs catalytically active sites. MOFs could be broadly divided into pure MOFs, their composites, and MOFs coupled materials.…”

Developing sustainable energy solutions to safeguard the environment is a critical ongoing demand. Electrochemical water splitting (EWS) is a green approach to create effective and long-lasting electrocatalysts for the water oxidation process. Metal organic frameworks (MOFs) have become commonly utilized materials in recent years because of their distinguishing pore architectures, metal nodes easy accessibility, large specific surface areas, shape, and adaptable function. This review outlines the most significant developments in current work on developing improved MOFs for enhancing EWS. The benefits and drawbacks of MOFs are first discussed in this review. Then, some cutting-edge methods for successfully modifying MOFs are also highlighted. Recent progress on nickel (Ni) and iron (Fe) based MOFs have been critically discussed. Finally, a comprehensive analysis of the existing challenges and prospects for Ni-and Fe-based MOFs are summarized.

“…In another study, Marti et al found that substituting a fraction of Mg with Ni in Mg-MOF-74 enhanced structural stability under moist conditions, further suggesting the potential for tailored stability through bimetallic modifications. Recently, our team successfully synthesized mesoporous Ce-BTC MOFs and used them as templates for CeO 2 catalysts for the water gas shift reaction and CO 2 methanation. , Inspired by analogous observations from the Ce-BTC MOF, we aimed to enhance the properties of these MOFs by introducing a secondary metal, such as Cu, through the modulation of metal nodes and organic ligands under hydrothermal conditions. Thus, here, we focused on producing CuCe-BTC with different Cu/Ce ratios and compared its properties and CO 2 adsorption with the monometallic MOF.…”

Metal−organic frameworks (MOFs) are highly regarded as valuable adsorbent materials in materials science, particularly in the field of CO 2 capture. While numerous singlemetal-based MOFs have demonstrated exceptional CO 2 adsorption capabilities, recent advancements have explored the potential of bimetallic MOFs for enhanced performance. In this study, a CuCe-BTC MOF was synthesized through a straightforward hydrothermal method, and its improved properties, such as high surface area, smaller pore size, and larger pore volume, were compared with those of the bare Ce-BTC. The impact of the Cu/ Ce ratio (1:4, 1:2, 1:1, and 3:2) was systematically investigated to understand how adding a second metal influences the CO 2 adsorption performance of the Ce-BTC MOF. Various characterization techniques, including scanning electron microscopy, transmission electron microscopy, powder X-ray diffraction, thermogravimetric analysis, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and N 2 BET surface area analysis, were employed to assess the physical and chemical properties of the bare Ce-BTC and CuCe-BTC samples. Notably, CuCe-BTC-1:2 exhibited superior surface area (133 m 2 g −1 ), small pore size (3.3 nm), and large pore volume (0.14 cm 3 g −1 ) compared to the monometallic Ce-BTC. Furthermore, CuCe-BTC-1:2 demonstrated a superior CO 2 adsorption capacity (0.74 mmol g −1 ), long-term stability, and good CO 2 /N 2 selectivity. This research provides valuable insights into the design of metal-BTC frameworks and elucidates how introducing a second metal enhances the properties of the monometallic Ce-BTC-MOF, leading to improved CO 2 capture performance.
