Published: Jan. 7, 2025

Abstract Advanced Oxidation Processes (AOPs) are promising for treating persistent pollutants, yet challenges arise due to the step-wise oxidants activation process, which traditional single-active-center catalysts struggle facilitate effectively. Recently, dual-active-center have emerged as a solution by enabling synergistic reactions. This review covers advances in these catalysts, their co-catalytic mechanisms, and applications electro-Fenton, photocatalytic, peroxymonosulfate-, pollutant-as-electron-donor based Fenton-like processes, along with active site design considerations future challenges.

Carbon Defects-Enriched Nbc-C3n5@Comn with Ultrafast Modulation of Redox Couples for Efficient Degradation of Contaminant

Published: Jan. 1, 2024

The sluggish cycling of redox couples is a primary cause the inefficiency catalysts in sulfate radical-based advanced oxidation processes (SR-AOPs). Herein, carbon defects-enriched NBC-C3N5@CoMn (NCC) was synthesized via self-assembly method. electron trap effect induced by defects facilitates efficient photo-Fenton-like during degradation, enabling self-regeneration NCC. reductive (Co(II) and Mn(II)) are continuously replenished after degradation. CoMn LDH within NCC serves as active site to generate •OH, SO4•- 1O2, directing degradation process through continuous gain loss electrons. Carbon defects-induced traps accelerate transfer continuously, promoting operation system. Simultaneously, establishment an internal electric field also expedites transfer. Density functional theory (DFT) confirmed exhibits lower adsorption energy higher efficiency. This work represents novel photocatalyst with self-renewable character, offering perspective for regulation SR-AOPs realize sustainable
