Recent advances on cobalt metal organic frameworks (MOFs) for photocatalytic CO2 reduction to renewable energy and fuels: A review on current progress and future directions

Advances in Titanium Carbide (Ti3C2Tx) MXenes and Their Metal–Organic Framework (MOF)-Based Nanotextures for Solar Energy Applications: A Review

“…Upon successful light harvesting, electrons are excited with sufficient energy to transverse the E bg from the VB or HOMO to the conduction band (CB) or LUMO. On the other hand, the photogenerated holes are then left behind in the VB or HOMO . Following the charge excitation step where electron/hole pairs are formed, there are two possibilities that may occur, which is the favorable utilization of electron/hole pairs for redox reactions or the unfavorable recombination of charge carriers leading to loss of energy.…”

“…2D MOFs have a few beneficial properties as an efficient photocatalyst, such as high exposed surface area to light irradiation and reactants, as well as excellent electron transferability. , Finally, 3D MOFs are held together by strong chemical bonds, which come together to form a highly complicated network structure. These polyhedrons boast an extremely high surface area, with uniform pore size distributed all over the surface of the MOF . Nevertheless, the morphology and dimensions of MOFs can be further regulated via two main approaches which is (1) modification of synthesis parameters and (2) introduction of additives.…”

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.…”

Monochromatic light-enhanced photocatalytic CO2 reduction based on exciton properties of two-dimensional lead halide perovskites

“…[3][4][5][6][7][8] The conversion of CO 2 into valuable solar fuels by photocatalysts simultaneously mitigates global warming and provides an energy source in an environmentally friendly manner. 2 In recent years, many photocatalysts have been reported for solar-driven photocatalytic CO 2 reduction, such as metal oxides, 9,10 metal sulfides, 11,12 metal-organic frameworks (MOFs), 13 graphene oxides, 14 graphene nitrides, 15 etc. 1,16 Nevertheless, traditional photocatalysts suffer from low surface-reactive reaction sites, inefficient light harvesting and rapid recombination of electron-hole pairs, which causes their photocatalytic activity to deteriorate.…”
