Ultra-thin and ultra-long α-MnO2 nanowires for pseudocapacitor material
Single phase, ultra-thin, and ultra-long α-MnO 2 nanowires were synthesized by facile method and investigated as an electrochemical pseudocapacitor active material. Structural characterizations reveal that the α-MnO 2 has a narrow size distribution of ˂5 nm and around 20–30 μm in length. A maximum s...

Summary: | Single phase, ultra-thin, and ultra-long α-MnO
2
nanowires were synthesized by facile method and investigated as an electrochemical pseudocapacitor active material. Structural characterizations reveal that the α-MnO
2
has a narrow size distribution of ˂5 nm and around 20–30 μm in length. A maximum specific capacitance of 495 F g
−1
can be achieved at a scan rate of 2 mV s
−1
by cyclic voltametrically. The α-MnO
2
nanowires exhibit excellent electrochemical performance at various current densities and good cycling ability. These results indicate that the α-MnO
2
nanowires are a promising candidate for the supercapacitor electrode active material. |
