Fluorescence nanoscopy unveils the black box of industrial zeolite catalysts:Mechanisms and optimization of mass transfer-acidity-coke formation
摘要
Abstract
The performance of industrial zeolite catalysts,typically exemplified by fluid catalytic cracking(FCC)catalysts,is governed by microscopic behaviors such as mass transfer,acidity and coking.Conventional characterization techniques exhibit limitations in elucidating the structure-performance relationships.So,recent advances in super-resolution fluorescence imaging for deciphering the key microscopic processes are systematically summarized in this review:(1)Mass transfer diffusion behavior:the heterogeneous diffusion of reactant molecules within hierarchical pore networks are revealed;(2)Acid site accessibility:nanoscale localization of acid sites and visualization of their accessibility are achieved;(3)Coking behavior:the spatiotemporal evolution mechanism of coke species on the catalysts are identified.Furthermore,the review elaborates on how super-resolution imaging deepens the understanding of fundamental catalytic mechanisms at the nanoscale,providing theoretical support for the rational design of high-performance catalysts-such as pore structure optimization,acid site regulation,and coking suppression-and concludes with an outlook on current challenges and future directions.关键词
