Tuning the optical properties of the zirconium–UiO-66 metal–organic framework for photocatalytic degradation of methyl orange

Tunable chiral metal organic frameworks toward visible light–driven asymmetric catalysis

“…S32) ( 6 ). Next, the chiral MOFs would accept a photon from a light source and cause charge separation, where the hole is located at the HOCO, and the electron reduces the metal ions ( 37 , 51 – 54 , 58 , 59 ). Then, the electron is further transferred to the diethyl bromomalonate (fig.…”

Sorption and photodegradation under visible light irradiation of an organic pollutant by a heterogeneous UiO-67–Ru–Ti MOF obtained by post-synthetic exchange

“…These compounds are widely used in the textile industry and according to several studies [1][2][3] textile dyes represent one of the largest groups of toxic organic compounds that contribute to water pollution. While some studies have shown promising results on the degradation and the sorption of these compounds, [4][5][6][7] there is still the need to work specially on the energy conversion efficiency and on the harvesting capacities of the materials since the quantum yield is low due to the limitations of the usual materials for photo-catalysis. 8 Moreover, a good number of the reported systems only work on the UV spectra of light which limits the application of these materials due to a low conversion yield.…”

Synthesis, characterization, and luminescent properties of two new Zr(IV) metal–organic frameworks based on anthracene derivatives

“…Synthesis of the 2,6-MOF and 1,4-MOF was adopted from previously reported methods for the UiO-66 framework with minor modifications. [9][10][11] Briefly, for the 2,6-MOF, 0.1 mmol ZrCl 4 and 0.1 mmol 2,6-ADCA were dissolved in 5 mL DMF along with 60 equiv formic acid as the modulator. The mixture was sonicated for 15 min followed by heating at 120°C for 24 h. To synthesize the 1,4-MOF, 0.1 mmol ZrCl 4 , 0.1 mmol 1,4-ADCA, and 80 equiv acetic acid were added to 3 mL DMF, the mixture was sonicated for 15 min, and then, it heated at 100°C for 12 h. The PXRD patterns of the 2,6-MOF and 1,4-MOF are shown in Figs.…”
