Interfacial Reaction of Atmospheric Micro/Nano Particles and Significance of Mineral Coevolution |
| |
| Abstract: | This paper presents the characteristics of atmospheric aerosols, the interfacial reaction between particles and the significance of coevolution of minerals, focusing on the size distribution and mineral composition of atmospheric particles, and characteristics of the products and key chemical processes of the interfacial reaction between the atmospheric particles and common toxic and harmful gases. In addition, the convergence role, adjustment mechanism, and catalystic effect of mineral particles on the aerosol formation process, and the synergistic reaction mechanism between SO2 and NOx in the atmosphere are summarized. Furthermore, the effects of micro/nano particles on the formation of secondary organic aerosols and the combination and coevolution of interfacial reaction products between atmospheric and mineral phases are analyzed. This review can provide guidance for further research on the process of atmospheric particulate matter reacting with trace polluted gases in the atmosphere to form secondary aerosols and then affecting the chemical composition of the atmosphere, and it is also of environmental significance since it facilitates future studies of both the micro-interface chemistry reaction of the surface characteristics of the atmospheric mineral particles in the complex pollutants and the combined effects of mineral dust-pollutant aerosol system in fog-haze formation, transformation, particle production and blocking behavior. |
