Special Issue Information

Dear Colleagues,

Metal–organic frameworks (MOFs) are emerging as excellent and promising heterogeneous catalysts due to their high surface areas, tunable pore sizes, diverse organic–inorganic ingredients, and dispersed active centers. In addition, MOFs can act as versatile precursors or sacrificial templates for preparing various functional materials with unique structures (e.g., porous structure) to achieve highly efficient catalysis.

This Special Issue of Nanomaterials titled “Synthesis and Applications of Metal-Organic Framework Based Materials and Related Porous Materials (2nd Edition)” welcomes authors to share their current research in the design, characterization, and application of novel MOF-based materials and related porous materials, including but not limited to thermal catalysis and photo-, electro-, and photo-electrocatalysis, which are mainly focused on the production of renewable energy and valuable chemicals.

The urgent need for sustainable CO2 conversion technologies has driven the development of advanced photocatalysts that harness solar energy. This study employs a CTAB-assisted solvothermal method to fabricate a Z-scheme heterojunction Fe-MOFs/VO-Bi2WO6 (FM/VO-BWO) for photocatalytic CO2 reduction. Positron annihilation lifetime spectroscopy (PALS) was employed to confirm the existence of oxygen vacancies, while spherical aberration-corrected transmission electron microscope (STEM) characterization verified the successful construction of heterointerfaces. X-ray absorption fine structure (XAFS) spectra confirmed that the defect configuration and heterostructure changed the surface chemical valence state. The optimized 1.0FM/VO-BWO composite demonstrated exceptional photocatalytic performance, achieving CO and CH4 yields of 60.48 and 4.3 μmol/g, respectively, under visible-light 11.8- and 1.5-fold enhancements over pristine Bi2WO6. The enhanced performance is attributed to oxygen vacancy-induced active sites facilitating CO₂ adsorption/activation. In situ molecular spectroscopy confirmed the formation of critical CO2-derived intermediates (COOH* and CHO*) through surface interactions involving four-coordinated and two-coordinated hydrogen-bonded water molecules. Furthermore, the accelerated interfacial charge transfer efficiency mediated by the Z-scheme heterojunction has been conclusively demonstrated. This work establishes a paradigm for defect-mediated heterojunction design, offering a sustainable route for solar fuel production. Full article
