Indirect Z-scheme heterojunction of NH2-MIL-125(Ti) MOF/g-C3N4 nanocomposite with RGO solid electron mediator for efficient photocatalytic CO2 reduction to CO and CH4

A super-hydrophilic NH2-MIL-125 composite film with dopamine-modified graphene oxide is used for water treatment

“…The peak values of the prepared NH 2 -MIL-125(Ti) at 6.81, 9.61, 11.61, 16.51, and 17.91 correspond to the (101), ( 200), (211), ( 222) and (312) planes. [44][45][46][47] This is in line with the literature consulted. In addition, for the composite material, with an increase in the NH 2 -MIL-125(Ti) content, the peak in M0 is continuously enhanced, and the peak of RGO Fig.…”

Advances for CO2 Photocatalytic Reduction in Porous Ti-Based Photocatalysts

“…(e) Schematic depict of charge carrier transfer of g-C 3 N 4 -RGO-NH 2 -MIL-125­(Ti) during CO 2 photoreduction. Reproduced with permission from ref . Copyright 2021 Elsevier.…”

“…The presence of RGO not only acts as a photosensitizer for enhancing the utilization of the solar light but also accelerates the mobility and separation of the charges, resulting in an increased production rate of CH 3 OH (14.75 μmol h –1 using 5 mg of catalyst). On this basis, the Z-scheme photocatalyst of NH 2 -MIL-125­(Ti) coupled g-C 3 N 4 with an RGO mediator was well-designed via a facial hydrothermal method for CO 2 photoconversion (Figure e) . The optimal g-C 3 N 4 -RGO-NH 2 -MIL-125­(Ti) composite showed an enhanced selectivity toward CO with a production rate of 9.59 μmol h –1 using 0.1 g of catalyst under visible light irradiation.…”

Visible-light-driven sonophotocatalysis for enhanced Cr(vi) reduction over mixed-linker zirconium-porphyrin MOFs

“…Metal-organic frameworks (MOFs), as an emerging series of crystalline hybrid materials, possess tunable pore size, high surface areas and powerful designability showing strong application potential in photocatalytic fields, such as carbon dioxide reduction, organic pollutant degradation, Cr(VI) reduction and so on. [14][15][16][17][18][19] Among various MOFs, zirconiumporphyrin MOFs has aroused tremendous attention because of their robust nature, excellent light adsorption and outstanding photocatalytic activities. [20][21][22][23][24] As a heterocyclic organic compound, porphyrin possesses an 18-electron conjugated π system, which improves the electron mobility in the ring, and in turn endows MOFs with excellent electron migration and energy transfer properties.…”
