Opposite particle size effects on the adsorption kinetics of ZIF-8 for gaseous and solution adsorbates†
Abstract
ZIF-8 shows complete opposite particle size effects on the adsorption kinetics for two different adsorbates. Smaller ZIF-8 particles favor fast I3− uptake in aqueous solution while larger, less defective ZIF-8 particles exhibit faster adsorption kinetics for gaseous H2, which suggests different adsorption mechanisms for the two adsorbates.
