Abstract

Conventionally, ZIF-8 particles have been prepared in batch solvothermal reactors, imposing limitations on the stability to achieve large-scale, rapid, and reproducible synthesis. In this study, ZIF-8 nanoparticles with narrow particle size distribution were produced continuously in a tubular reactor by a novel solvo-jet process, which combined solvothermal reaction for nucleation and vaporization-induced solid-liquid reaction for crystal growth and facet development. The size and morphology of the product ZIF-8 nanoparticles were significantly affected by the reaction temperature and residence time. With increasing reaction temperature from 120. °C to 180. °C, the average particle size decreased from 155. nm to 35. nm. The mechanism of crystal formation by continuous solvo-jet process was studied. Furthermore, gas separation properties of the product ZIF-8 nanoparticles were investigated by the adsorption of various gases.
