In situ growth of ZIF-8 nanocrystals on layered double hydroxide nanosheets for enhanced CO2 capture†
Abstract
A hexagonal nanosheet LDH@ZIF-8 composite was fabricated by in situ growth of ZIF-8 on Zn–Al LDH without adding any zinc precursor, and exhibited a CO2 adsorption capacity of 1.0 mmol g−1 at room temperature and 1 bar, which was significantly higher than that of pure Zn–Al LDH or ZIF-8, indicating a synergy between ZIF-8 and Zn–Al LDH.
