UiO-type Zr-BDC MOFs have garnered the interest of scientific community due to their exceptional diversity in composition, structure, and chemical environment, as well high thermal stabilities. This work demonstrates sustainable synthesis a series nanocrystalline/semicrystalline UiO-66(Zr) metal–organic frameworks (MOFs) under facile conditions—specifically at room temperature, water, with yield, without use modulators or toxic byproducts. The involves either deprotonating linker utilizing various ratios water DMF solvents. as-prepared materials obtained from both strategies share key structural features conventional short- medium-range physicochemical properties, while exhibiting significant differences crystallinity textural properties. Nonetheless, generally lack long-range order (semicrystalline), particular these synthesized following deprotonation strategy. However, prepared using mixed solvent strategy seem exhibit characteristics nanocrystalline UiO-66(Zr). Overall, approaches successfully addressed challenges related highly sought-after Zr-based (MOFs). Some MOF were tested for photodegradation rhodamine B (RhB) mercury light irradiation, evidencing photocatalytic efficiency up 75 ± 0.078% within 120 min pseudo-first-order model. suggests an interaction between photocatalyst RhB dye, involving electron injection ability ligand-to-metal charge transfer (LMCT), which enhances efficient degradation RhB. trapping experiments indicated that superoxide radicals (•O2−) photogenerated holes (h+) are crucial Moreover, showed good recyclability across five cycles. A plausible reaction mechanism has been proposed explain findings.
