| Abstract Scope |
Metal-organic frameworks (MOFs) are crystalline porous materials composed of metal ion centers and organic linkers. The intrinsic high surface area and controllable pore size of MOF structures by linker length variation make them ideal in porous templates preparation.
In this work, we adopt a rational strategy to fabricate NiCo2O4/Co3O4-rGO supercapacitor electrodes. Highly porous ZIF-67 nanocrystals are firstly produced through the coordination modulation process. By carefully etching these structures, ZIF-67/Ni-Co layered double-hydroxide template is formed. The as-prepared templates are subsequently calcinated to obtain the NiCo2O4/Co3O4 nanocomposite. To prevent particle agglomeration and improve the charge transfer, we functionalize the surface of as-prepared nanostructures through a silanization process. We mixed the surface-treated nanostructure with graphene oxide dispersion to form a self-assembled NiCo2O4/Co3O4-rGO composite electrode. |
