Facile synthesis of ZnO@ZIF core–shell nanofibers: crystal growth and gas adsorption

ZnO@ZIF-8 core–shell nanofibers were manufactured via direct growth of ZIF-8 on eletrospun ZnO nanofibers for the first time. The versatility of this synthesis strategy for other ZnO@ZIF nanofibers was also demonstrated. The as-synthesized ZnO@ZIF-8 nanofibers exhibit enhanced CO2 adsorption ability and unique adsorption preference as compared to pristine ZnO nanofibers.
