ZIF-8 metal organic framework composites as hydrogen evolution reaction photocatalyst: A review of the current state

ZIF-8 metal organic framework materials as a superb platform for the removal and photocatalytic degradation of organic pollutants: a review

“…48,[54][55][56][57][58] ZIF-8 MOFs can be synthesized using different solvents and solvent-free methods including solvothermal, hydrothermal, ionothermal, sonochemical, accelerating agent, mechanochemical and direct solvent-free procedures. 15 Their synthesis is dependent on specic catalytic reaction conditions. For instance, solvent-free synthesis leads to the formation of multi-variate ZIF materials and their pores are not partially covered by organic solvents.…”

“…[1][2][3][4][5][6] Accordingly, various technologies have been used for wastewater treatment to degrade or remove these persistent organic pollutants such as adsorption, 7 ltration, 8 membrane technology, 9 coagulation, 10 electrochemical oxidation 11,12 and photocatalytic degradation. [13][14][15][16] Besides, the transformation of concentrated or divided contaminants into non-toxic materials is a critical issue. Considering both energy and the economy, it is desirable to treat pollutants through adsorption or photocatalytic reactions.…”

Bismuth tungstate Bi2WO6: a review on structural, photophysical and photocatalytic properties

“…Photocatalysis involves using UV or visible light to activate a semiconductor material, which then promotes redox reactions that degrade organic molecules in an aqueous medium. [74][75][76][77] The semiconductor's electronic structure consists of a valence band and a conduction band separated by a band gap. Upon irradiation with photons having energy greater than or equal to the band gap, electrons move from the valence band to the conduction band, generating electronic holes.…”

“…102−104 The MOFs serve as active centers for the HER, whereas the carbon components provide the composite with electrical conductivity and stability. 46,105,106 In this regard, Yan et al 64 describe a unique technique attaching a nickel-MOF onto a substrate made of graphene oxide and incubating it to form a hybrid material called Ni 2 P/rGO. In an alkaline electrolyte, the synthesized catalyst manifests outstanding catalytic behavior for HER.…”

“…Carbon components like graphene and carbon nanotubes CNTs are a broad set of materials that, because of their remarkable qualities including noteworthy surface expanse, outstanding electrical conductivity, and excellent toughness, are commonly utilized in a diverse array of industries notably electrocatalysis. − As a consequence of the combined action of the two materials, the utilization of MOF composites with carbon materials as electro-catalysts for HER has shown encouraging results. − The MOFs serve as active centers for the HER, whereas the carbon components provide the composite with electrical conductivity and stability. ,, In this regard, Yan et al describe a unique technique attaching a nickel-MOF onto a substrate made of graphene oxide and incubating it to form a hybrid material called Ni 2 P/rGO.
