C₃N₄ anchored ZIF 8 composites: photo-regenerable, high capacity sorbents as adsorptive photocatalysts for the effective removal of tetracycline from water

Abstract

C3N4–ZIF-8 porous architectures are developed for the efficient adsorption and sunlight induced photocatalytic degradation of tetracycline.

Hydrogen production and photocatalytic activity of g‐C3N4/Co‐MOF (ZIF‐67) nanocomposite under visible light irradiation

“…While, the g‐C 3 N 4 /ZIF‐67 catalyst exhibited the lowest intensity as compared to g‐C 3 N 4 , designating remarkable repression for the recombination of e − /h + pairs. As a result, the PL results confirmed the effective coupling of the g‐C 3 N 4 and ZIF‐67 in hybrid and formation of heterostructures . PL result suggests that the prominent charge carrier efficiency of g‐C 3 N 4 /ZIF‐67 is enhanced after the surface coupling of ZIF‐67.…”

ZIF‐67‐Derived 3D Hollow Mesoporous Crystalline Co3O4 Wrapped by 2D g‐C3N4 Nanosheets for Photocatalytic Removal of Nitric Oxide

“…The 3D rhombic dodecahedron ZIF‐67 crystals prepared by the in situ growth method are uniformly wrapped by the 2D CN pleat nanosheets with minimal agglomeration (Figure c,d, Figure b). The CN‐ZIF‐67 composite is tightly bound by electrostatic attraction and π–π interactions . After low‐temperature calcination in air, ZIF‐67 was oxidized to inorganic CO (Figure e,f, Figure c,d), where part of the H‐mim organic ligand was exchanged by O 2 .…”

“…The abundant nitrogen (N) coordination sites on the surface of CN make it easy to fix Co 2+ into tri‐s‐triazine units by electrostatic interaction. ZIF‐67 was then dispersed uniformly in CN by π–π interactions after the ligand was added . The in situ growth method allows ZIF‐67 to adhere firmly to CN, and the pleated CN guarantees the omnidirectional contact of the ZIF‐67 with CN.…”

Facile fabrication of BUC‐21/g‐C3N4 composites and their enhanced photocatalytic Cr(VI) reduction performances under simulated sunlight

“…Therefore, some researches have focused on the combination of g‐C 3 N 4 and MOF materials to improve the photocatalytic efficiency considering MOFs can transfer photoelectrons rapidly as a result of their metal nodes. Some composites like MIL‐53(Al)/g‐C 3 N 4 , g‐C 3 N 4 /MIL‐53(Fe), MIL‐125(Ti)/g‐C 3 N 4 and ZIF‐8(Zn)/g‐C 3 N 4 were prepared for the degradation of organics and effective reduction of Cr(VI). BUC‐21 is a chemically stable two‐dimensional MOF synthesized by our group, which exhibits superior photocatalytic performance under UV light irradiation towards Cr(VI) reduction and organic decomposition .…”
