Synthesis of ZIF-8 Coating on ZnO Nanorods for Enhanced Gas-Sensing Performance
Bo Huang, Wen Zeng, Yanqiong Li
Abstract
Firstly, ZnO nanorods were prepared by a relatively simple method, and then self-sacrificed by a water bath heating method to generate a commonly used porous ZIF-8 and firmly attached to the ZnO surface. The successful synthesis of synthetic composites was demonstrated with various detection methods. The gas-sensing results show that the ZIF-8-coated ZnO with a core-shell structure exhibits better response than the raw ZnO because of the increased specific surface area and active sites.
