Abstract

Large-diameter carbon nanotube (CNT) paper was used as a porous and conductive template to obtain vertically aligned Ni₂(OH)₂CO₃ nanowire array shells, which could be further converted into highly active Ni(OH)₂ nanosheets by a cyclic voltammetry strategy. The as-prepared hierarchical nanostructure showed superior electrochemical performance for the electrodes of supercapacitors.
