Special Issue Information

Dear Colleagues,

Metal–organic frameworks (MOFs) are a class of crystalline materials composed of metal ions or clusters coordinated to organic ligands, forming highly porous structures. Their exceptional surface area, tunable pore size, structural diversity, and chemical versatility make MOFs ideal candidates for advanced catalysis technologies. In catalysis, MOFs offer unique advantages which are outlined below.

  1. Tailorable Active Sites: By carefully selecting metal centers and organic linkers, MOFs can be designed with specific active sites for targeted catalytic reactions.
  2. High Surface Area and Porosity: The large internal surface areas (some MOFs reach a specific surface area of 10,000 m²/g) and interconnected pore networks allow for efficient mass transport and high catalyst loading.
  3. Structural Tunability: MOFs' structures can be modified post-synthetically (e.g., by doping, functionalization, or defect engineering) to enhance catalytic activity, selectivity, and stability.
  4. Single-Atom Catalysis: MOFs can anchor isolated metal atoms in well-defined coordination environments, maximizing atom utilization and creating highly efficient catalysts.
  5. Thermal and Chemical Stability: Advances in MOF chemistry have led to materials that remain stable under harsh catalytic conditions, including high temperatures and reactive chemical environments.

In addition, applications of MOF-based catalysis technologies include the following:

  1. Energy Conversion: MOFs are employed in electrocatalysis (e.g., hydrogen evolution reaction (HER), oxygen evolution reaction (OER), CO2 reduction) and photocatalysis for sustainable energy generation.
  2. Environmental Remediation: MOFs catalyze the degradation of pollutants and toxic chemicals in air and water.
  3. Fine Chemical Synthesis: MOF catalysts enable highly selective organic transformations, such as oxidation, hydrogenation, and C–C bond formation.
  4. Biomimetic Catalysis: Certain MOFs mimic the function of natural enzymes ("MOFzymes"), offering high specificity and mild operating conditions.

Recent trends have also focused on MOF-derived materials, where MOFs are used as precursors to create porous carbons, metal oxides, metal sulfides, and composite nanostructures with outstanding catalytic properties after thermal or chemical treatment. Overall, MOF-based catalysis technologies are revolutionizing the field of heterogeneous catalysis by offering unprecedented control over structure, composition, and functionality at the molecular level.

Abstract
This study systematically investigates how organic ligand modifications—chain length adjusting and functional group incorporation—regulate the catalytic performance of UiO-66 derivatives for CO2-to-dimethyl carbonate (DMC) conversion. Through multi-technique characterization (Py-IR, TGA, FT-IR, XPS, etc.) and catalytic tests, Lewis acid/basic sites (LAS/LBS), bulk [...] Read more.
This study systematically investigates how organic ligand modifications—chain length adjusting and functional group incorporation—regulate the catalytic performance of UiO-66 derivatives for CO2-to-dimethyl carbonate (DMC) conversion. Through multi-technique characterization (Py-IR, TGA, FT-IR, XPS, etc.) and catalytic tests, Lewis acid/basic sites (LAS/LBS), bulk defects and electron density effects were identified as the three key factors to govern the catalytic activity. The bulk defects were believed to enhance mass transfer. Notably, MOF-801 (shortest ligand) and UiO-66-Br (electron-withdrawing-Br) achieved the highest TOFs of 0.86 h−1 and 1.10 h−1, respectively. While LAS/LBS and electron-rich Zr clusters promote methanol activation, defect-enhanced mass transfer dominated over electronic effects in boosting DMC yield. These insights highlight the tunability of MOFs for CO2 utilization via rational ligand design. Full article

The development of efficient, highly stable photocatalysts is essential to address the two challenges of environmental remediation and renewable energy. Structurally strong Zeolitic Imidazolate Framework-8 (ZIF-8) has intrinsic drawbacks, including a large bandgap and fast charge-carrier recombination. This paper presents a highly efficient approach to designing the optoelectronic behaviour of ZIF-8 via controlled nickel doping. Ni(x)-ZIF-8 (0, 2.5, 5, 7.5, and 10 mol, x), and bimetallic metal–organic frameworks were prepared via a simple room-temperature process. Through adequate characterization, the incorporation of Ni2+ into the ZIF-8 lattice has been demonstrated to be successful, resulting in substantial structural and electronic changes. Framework integrity was confirmed using XRD and FTIR analysis, which revealed increased microstrain and the formation of Ni-N bonds. Most importantly, UV-Vis spectrophotometry and electrochemical studies indicated that the bandgap was systematically narrowed: a pristine ZIF-8 had a high bandgap of 3.65 eV, and a Ni(10)-ZIF-8 had a low bandgap of 3.23 eV, while charge-transfer resistance was reduced significantly. All these synergies led to high photocatalytic performance. The best Ni(2.5)-ZIF-8 catalyst achieved a desirable result, degrading methylene blue to more than 98.5%, which was far superior to that of the pure framework. Moreover, the hydrogen evolution reaction (HER) showed higher electrocatalytic activity, with a significantly lower overpotential and higher current density. This article defines Ni doping as an effective route to convert ZIF-8 into a high-performance, dual-functional photocatalyst. It opens the door to implementing solar-powered environmental remediation and hydrogen generation using ZIF-8. Full article

In this study, cerium-based metal–organic frameworks (MOFs), cerium terephthalate (CeTPA), were synthesized and incorporated into nanofibers via electrospinning using poly(methyl methacrylate) (PMMA). The synthesized materials were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), and Tauc plot analysis. The electrospun CeTPA nanofibers exhibited superhydrophobic properties, with water contact angles exceeding 150°. The adsorption and catalytic performance of the nanofibers were assessed for dye removal using Congo red (CR) and methylene blue (MB) as model organic pollutants. Adsorption studies demonstrated negligible dye uptake due to the hydrophobicity of the fibers, while catalytic degradation experiments in the presence of hydrogen peroxide (H2O2) showed significant degradation of CR but limited effectiveness against MB, offering high selectivity toward anionic dyes. Structural and optical characterizations confirmed the stability and catalytic activity of CeTPA nanofibers, highlighting their potential for selective dye degradation in wastewater treatment applications.
