碳基量子点在界面光催化中的研究进展
A review of carbon-based quantum dots for interfacial photocatalysis
摘要
Abstract
Carbon-based quantum dots(C-QDs)have attracted growing attention in photocatalysis because of their tunable surface chemistry,unique electronic structure,and ability to regulate interfa-cial charge transfer.In recent years,their role has moved beyond that of simple light absorbers or general performance enhancers,and they are in-creasingly regarded as engineered interfacial com-ponents that can control charge separation,reac-tion-site microenvironments,and product selectiv-ity.However,the broad claim that C-QDs im-prove photocatalytic performance often lacks clear mechanistic validation,which limits the ability to compare and reproduce reported studies.Recent advances in C-QD-based photocatalysis are reviewed with particular attention to the experimental evidence supporting their proposed roles and mechan-isms.Three roles are considered:(a)electron sinks or charge reservoirs,(b)interfacial bridges or charge-transfer conduits,and(c)adsorption or microenvironment modulators.The evidence needed to support these assignments is then discussed,including measurements of band energetics and carrier dynamics,characterization of interfacial coupling,identification of reaction inter-mediates under working conditions,isotope-labeling experiments,and carbon balance analysis.Representative applications in hydrogen evolution,CO2 photoreduction,and pollutant degradation/photo-enhanced advanced oxidation processes are also ana-lyzed to clarify how C-QD roles should be matched with reaction-specific metrics.Finally,the review identifies several recur-ring problems that hinder mechanistic interpretation and comparison between studies:C-QDs are often assigned different func-tions without sufficient evidence;Z-scheme and S-scheme labels are sometimes used without directly verifying the proposed charge-transfer pathways;reaction intermediates and catalyst behavior are not always examined under actual reaction condi-tions;and photocatalytic performance is reported using inconsistent metrics and test conditions.This review aims to provide practical guidance for building reliable structure-function relationships and for designing next-generation C-QD-based pho-tocatalysts with clearer mechanisms,stronger reproducibility,and greater application potential.关键词
