UiO-66-type MOFs were synthesized using low and high concentrations of the modulating agent (acetic acid). Characterization by X-ray diffraction (XRD), in situ XRD, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and nitrogen physisorption revealed significant differences in surface area, porosity, and structural defect density. These tunable properties make the MOFs strong candidates as catalytic supports, offering an alternative to conventional zirconia in the CO₂ hydrogenation to methanol reaction, particularly due to their ability to incorporate copper ions via ion exchange, making them promising systems for catalytic applications.
