卷烟滤棒中降焦减害功能多孔吸附材料的研究进展OA

Porous adsorbent materials are a type of functional materials in cigarette filter rods,whose structures and types directly affect the retention efficiency of harmful substances in cigarette smoke.This paper systematically reviews the adsorption mechanism and research progress of functional porous materials used in cigarette filter rods;the adsorption and removal of harmful components in cigarette smoke is a synergistic process of kinetic mass transfer and thermodynamic adsorption,which is mainly affected by the pore structure,molecular structure and functional adsorption sites of adsorbent materials.Through strategies such as multi-level pore design,surface functionalization modification,anchoring of molecular specific recognition sites,and multi-component composite,we can functionally construct these three types of porous adsorbent materials,namely inorganic,organic,and organic-inorganic hybrids,to improve the selective adsorption and retention efficiency of harmful components in cigarette smoke.In the future,it is necessary to conduct more in-depth research on the dynamic adsorption mechanism of the complex matrix of cigarette smoke to realize the precise and controlled preparation of adsorbent materials for cigarette filter rods and the precise and efficient retention of harmful smoke components,as well as provide a reference for the development of tar and harm reduction technologies in the tobacco industry.
