Fabrication of polypyrrole-sensitized Ag₃PO₄/g-C₃N₄ Z-scheme heterojunction for photocatalytic and antibacterial activity

Abstract

Ag3PO4/PPy/g-C3N4 nanocomposite synthesized by hydrothermal and in situ chemical oxidation polymerization exhibits tremendous photocatalytic activity, and photo-antimicrobial activity under visible light irradiation.

Facile construction of iron-based MIL-101@MIL-53 Z-scheme heterojunction for the efficient removal of tetracycline hydrochloride

“…Compared with traditional type-II heterojunctions, the Z-scheme and S-scheme heterojunctions exhibited a unique charge transfer pathway, resulting in stronger electron reducibility and hole oxidation ability. 17–19 In addition, the growth of another MOF on MOF (MOF@MOF) was considered a unique way to prepare MOF-based heterojunction with the minimum loss of porosity and uniform distribution of active sites. 20,21 Furthermore, the formation of well-defined contacts at the interface facilitated the charge transfer and restrained the charge recombination, which further enhanced the photocatalytic performance of the composite.…”
