High-density Co 3 O 4 nanowire arrays have been fabricated by a simple, solvent-free synthesis method inside the alumina pores. It has been found that the pore diameter played a key role in the formation of the Co 3 O 4 nanowires. When the same reaction was performed in the narrow pores of the AAO template ( 120 nm) were applied. Selected-area electron diffraction (SAED) patterns revealed that the nanowires were single-crystalline. Electrochemical measurements by an electrochemical workstation indicate that the specific capacitance characteristics of the as-prepared Co 3 O 4 nanowires are much higher than that of Co 3 O 4 particles.
