MIL-68(Fe) as an efficient visible-light-driven photocatalyst for the treatment of a simulated waste-water contain Cr(VI) and Malachite Green

Cr(VI) remediation from aqueous environment through modified-TiO2-mediated photocatalytic reduction

“…A highly effective iron metal-framework photocatalyst (MIL-68(Fe)) has been successfully prepared by Jing et al via a facile solvothermal method under acidic conditions [231]. The metal organic framework acts as an effective photocatalyst for Cr(VI) reduction and can remove different aqueous contaminants with malachite green (MG) as a scavenger.…”

Bidentate carboxylate linked TiO2 with NH2-MIL-101(Fe) photocatalyst: a conjugation effect platform for high photocatalytic activity under visible light irradiation

“…So, it has been applied for various areas such as adsorption [28,29], energy storage and catalysis applications [30,31]. Ti-MOFs [32,33], Zr-MOFs [34,35], Fe-MOFs [36] and Cu-MOFs [37] have been regarded as feasible photocatalysts owing to their suitable electron excitation structure from HOMO to LUMO under light irradiation. Specifically, Fe-MOFs provide remarkable achievements in photodegradation of organic pollutants under visible light due to the presence of extensive iron-oxo clusters [38].…”

Co3O4–Ag photocatalysts for the efficient degradation of methyl orange

“…In contrast, since previous research has reported that TiO 2 can be used for water splitting and organic pollutant degradation, 4,5 the use of semiconductors as photocatalysts has attracted increasing attention due to their perfect utilization of the clean and renewable solar energy. [6][7][8][9] However, TiO 2 can only absorb ultraviolet light due to its wide band gap ($3.2 eV). [10][11][12][13][14] Hence, various new types of semiconductors have been developed as photocatalysts to solve this problem.…”
