Cobalt oxide nanoparticles synthesized through simple microwave method are employed for supercapacitor studies. XRD analysis reveals the cubic phase of the synthesized nanoparticles. TEM image indicate uniform distribution of the nanoparticles. The blue shift of the band gap energy as obtained through optical absorption studies confirms the quantum confinement effect. PL spectra recorded at room temperature...
Porous hexagonal NiCo 2 O 4 nanoplates with an average diameter of about 100nm and average thickness of about 25nm have been successfully synthesized through a facile hydrothermal process and subsequent calcination in air. The calcination temperature involved has obvious affection upon the porous structures as well as the resultant capacitive performances. The NiCo 2 O ...
