| abstract |
The invention discloses a preparation method of a nickel-cobalt hydroxide nanosheet, which comprises the steps of respectively dissolving 2-methylimidazole and cobalt salt in water, mixing, adding nickel foam, stirring for reaction to obtain a Co-ZIF nanosheet, mixing the Co-ZIF nanosheet and the nickel salt in ethanol, and stirring at constant temperature to obtain a final product. The method is simple, convenient and environment-friendly, and the prepared hollow triangular nickel-cobalt hydroxide nanosheet is beneficial to contact between the electrolyte and the electrocatalytic material, and has good OER catalytic performance and high stability. |
