Significantly improved photocatalysis-self-Fenton degradation performance over g-C3N4 via promoting Fe(III)/Fe(II) cycle

In situ use of photocatalytically produced H2O2 for Fenton degradation of organic pollutants

“…This effect was ascribed to the presence of graphite carbon within the g-C 3 N 4 , which aided in the separation of charge carriers, thereby increasing the participation of photogenerated electrons in the reduction of Fe 3+ ions. 72 Similarly, Li et al developed the sliced g-C 3 N 4 nanosheets with spherical CdS (abbreviated as SCNO@CdS) nanoparticles embedded on them. These photocatalysts demonstrated effective in situ Fenton activity for RhB degradation using the H 2 O 2 generated on them.…”

Promising Materials for Photocatalysis‐Self‐Fenton System: Properties, Modifications, and Applications

“…Recently, Ma's group synthesized a high-efficient material applied in PSFs. The prepared graphitic carbon interface-modified g-C 3 N 4 (CUCN) immensely promoted Fe(III)/Fe(II) cycle, leading to 63.77% mineralization degree for RhB within 3 h. [108] However, due to the existing of electrostatic repulsion, some problems still persist in aforementioned type-II heterojunction including poor redox ability. [109] To overcome this shortcoming, [100] Copyright 2018, Elsevier.…”

Environmental applications of single-atom catalysts based on graphdiyne

“…101 In recent years, the 2D nonmetallic organic semiconductor g-C 3 N 4 has received significant attention due to its good physical and chemical properties. [189][190][191] However, it possesses poor conductivity and low separation efficiency, which can be overcome with the addition of GDY. 34 The excellent conductivity and carrier mobility of GDY offer a new approach to achieve the photocatalytic reduction of CO 2 .…”
