Construction of a PCN/Fe₂O₃/CdS double Z-type heterojunction photocatalyst and its application in the oxidative coupling reaction of benzylamine

Abstract

In this work, PCN/Fe2O3/CdS ternary heterojuction photocatalyst was constructed by introducing an appropriate amount of ferric oxide (Fe2O3) and cadmium sulfide (CdS) on porous carbon nitride (PCN), denoted as PCN/Fe2O3/CdS....

Recent advances in the heterogeneous photochemical synthesis of C–N bonds

“…Except for the abovementioned semiconductor materials such as carbon nitrides and TiO 2 , photocatalysts such as BiVO 4 , Fe 2 O 3 , CdS, and MOFs are often used to construct heterogeneous structures for heterogeneous photocatalytic imine oxidative coupling. [122][123][124][125][126] However, it is currently difficult to construct a specific type of heterojunction by design. In most cases, it is necessary to verify the type of heterojunction that has been synthesized by photodeposition or sacrificial agent experiments.…”

Controlled Synthesis and Visible-Light-Driven Photocatalytic Activity of BiOBr Particles for Ultrafast Degradation of Pollutants

“…Nevertheless, most of them suffer from some intrinsic drawbacks including low efficiency, expensive, fast recombination of photogenerated hole–electron pairs, poor light harvest ability. As a consequence, many strategies, such as band gap ( E g ) engineering, introducing luminescent materials, constructing heterostructure, and promoting charge separation efficiency via depositing metal ions, were proposed to settle these issues [ 8 , 9 , 10 , 11 ]. Although the photocatalytic behaviors of the semiconductors have been modified to a certain degree with the help of these aforementioned techniques, more efforts should be made to further elevate their photocatalytic activities as well as extend their vivid applications.…”
