Coated to perfection: Activated carbon (AC) with a nickel catalyst is coated in situ with herringbone carbon nanofibers (CNFs) through catalytic chemical vapor deposition from propane at 450 °C. The CNF/AC composite is implemented in supercapacitors, showing much higher power than the pristine AC, which is attributed to the presence of CNFs to enhance ion diffusion in the electrode and act as electronic bridges between AC particles (see picture).
