Highly flexible NiCo2O4/CNTs doped carbon nanofibers for CO2 adsorption and supercapacitor electrodes

Controllable synthesis of carbon nanofibers (CNFs) with hierarchical porosity and high flexibility are extremely desirable for CO2 adsorption and energy storage applications. Herein, we report a nickel cobaltite/carbon nanotubes doped CNFs (NiCo2O4/CNTs CNFs) mesoporous membrane that shows well developed flexibility, tailored pore structure, hydrophobic character, and high stability. Ascribed to these unique features, NiCo2O4/CNTs CNFs membrane shows high CO2 capture of 1.54 mmol/g at 25 degrees C and 1.0 bar, and electrochemical measurements for supercapacitors exhibit good performance with specific capacitances of 220 F/g (in 1 M KOH) at a current density of 1 A/g. The successful synthesis of such hybrid membrane provides new insight into development of various multifunctional applications. (C) 2016 Elsevier Inc. All rights reserved.
