Abstract MXenes are a new type of 2D transition metal carbon/nitride or carbonitride, which composed M n +1 AX phase material (MAX phase) through single‐layer thin‐layer nanosheets obtained by exfoliation. Owning to unique two‐dimensional layered structure, large specific surface area, excellent electrical conductivity and mechanical stability, the have quickly become research hotspot due their magnetic other properties, been widely used in many fields such as electrochemical sensors, energy storage, catalysis, adsorption. This article summarizes introduces preparation methods materials MXenes, focus on reviewing application progress sensors environmental field recent years, including detection biomarkers pollutants, adsorption heavy metals, radiation organic matter, selective carbon dioxide, membrane separation, electrocatalysis, photocatalysis, electromagnetic absorption shielding, etc. A summary review were conducted, finally existing problems future development at this stage analyzed.

Covalent Organic Frameworks: Synthesis and Applications for Photocatalysis

ChemPhotoChem, Год журнала: 2024, Номер unknown

Опубликована: Июнь 27, 2024

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, Год журнала: 2025, Номер unknown

Опубликована: Янв. 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.
