Abstract Covalent organic frameworks (COFs), newly developed materials, exhibit considerable promise in the field of catalysis. COFs captivating catalytic characteristics, including thermal and chemical stability, customizable porosities, ability to place active sites flexibly with tunable functions. To establish a connection between structure activity, this paper provides thorough justification planned creation covalent for photocatalysis, encompassing H 2 production, carbon dioxide reduction, pollutants reduction transformation substances. We have investigated that are within frameworks, metals, molecular catalysts, catalyst single atom (SACs); reactive skeleton/linkages; pendant groups. This exploration aims benefits using COF‐based catalysts compared traditional catalysts. Despite new advantages, numerous difficulties also been noted regard future. The objective review is make it easier design composite materials practical uses.

Recent Progress in Advanced Catalytic Strategies for C─F Bond Cleavage in Waste Refrigerants: A Review

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 28, 2025

Abstract The degradation of fluorinated refrigerants, known for their highly stable carbon‐fluorine (C─F) bonds, poses significant environmental and technical challenges. This review addresses these challenges by analyzing two core mechanisms: molecular polarization (MP) free radical attack (FRA), exploring applications in thermal catalytic photocatalytic processes. MP redistributes electron density to weaken C─F facilitating adsorption bond cleavage, while involves reactive species that directly break chemical bonds. However, both mechanisms have limitations: alone may lack the kinetic drive dissociation, radical‐based methods often suffer from low selectivity, short lifetimes, formation toxic intermediates. section on discusses how elevated temperatures enhance cleavage through MP, addressing accelerating dissociation. part focuses role light‐activated processes generating radicals breaking, with an emphasis visible ultraviolet light‐driven reactions. concludes potential hybrid systems combine processes, providing insights into complementary use persistent compounds.
