Double Z-scheme system of α-SnWO4/UiO-66(NH2)/g-C3N4 ternary heterojunction with enhanced photocatalytic performance for ibuprofen degradation and H2 evolution

The surface reconstruction induced enhancement of the oxygen evolution reaction on α-SnWO4 (010) based on a density functional theory study

“…Recent developments have demonstrated that the Z-scheme photocatalyst based on α-SnWO 4 is an effective catalyst for maximizing photocatalysis performance. 58 When two semiconductor photocatalysts differ in their work function, they are able to produce charge redistribution and generate an internal electric field. This effect may significantly impact the process of separating and transferring photogenerated charge carriers.…”

Metal–organic framework‐based heterojunction photocatalysts for organic pollutant degradation: design, construction, and performances

“…Recently, it has been observed that the activity of MOF@g-C 3 N 4 Z-scheme photocatalysts in the degradation of organic pollutants could be further improved by the addition of a third component to obtain ternary heterojunction. [175][176][177] Wei et al 177 showed that the use of the ternary composite ⊍-SnWO 4 /NH 2 -UiO-66/g-C 3 N 4 allows for excellent photoactivity in the degradation of ibuprofen that is approximately 5.84, 14.35, 4.23, and 2.03 times higher than those of g-C 3 N 4 , NH 2 -UiO-66, ⊍-SnWO 4 , and NH 2 -UiO-66/g-C 3 N 4 , respectively. This photocatalyst also demonstrated good activity in water splitting, providing a hydrogen evolution rate of 2105 μmol•g −1 •h −1 .…”

ZIF ‐67 derived hollow double‐shell core Co 3 O 4 modified g‐C 3 N 4 to construct p‐n heterojunction for efficient photocatalytic hydrogen evolution

“…Therefore, in recent decades, researchers have tried a series of methods to cope with the above challenges, such as adding active groups, structural defects, building interface heterojunctions and co‐catalyst modification, etc 20‐23 . And studies have found that the construction of interface heterojunction can enhance the separation and transfer capabilities of light‐induced carriers driven by the built‐in electric field, so that their electrons can be effectively used 24,25 …”

“…[20][21][22][23] And studies have found that the construction of interface heterojunction can enhance the separation and transfer capabilities of light-induced carriers driven by the built-in electric field, so that their electrons can be effectively used. 24,25 Metal organic framework (MOF) is a material composed of metal atoms or metal clusters and organic ligands or organic complexes. 26 The advantages of MOF materials are the rich pore structure and larger specific surface area, which allow the materials to expose more photoreaction sites when participating in the reaction.…”
