Continuous Nanobelts of Nickel Oxide-Cobalt Oxide Hybrid With Improved Capacitive Charge Storage Properties

This paper reports the synthesis of continuous nanobelts, whose thickness is less than half of its pore diameter, of a material hybrid composing of nanograins of nickel oxide and cobalt oxide by electrospinning technique and their capacitive charge storage properties. While the constituent binary me...
