Surfactant template preparation of NiO nanocrystals using a gas-liquid diffusion method and electrochemical performance

Surfactant Template Preparation by using a Gas-Liquid Diffusion method followed by calcinations could influent obviously on the morphology and structure of NiO nanocrystals. The electrochemical test results indicate that the dandelion-shaped NiO prepared with sodium dodecyl sulfate template exhibit obvious pseudo-capacitance reaction and possess the specific capacitances of 922 F g−1 at 2 A g−1.
