preparation of hollow spherical fluoride potassium nickel cobalt perovskite and its application to supercapacitor and catalyst

摘要

The present invention relates to the production of hollow spherical potassium fluoride nickel cobalt perovskite and its application to supercapacitors and catalysts, and is a hollow spherical form perovskite crystalline material having a composition of _{KNi 1-x} Co _x F _3-δ It can be used not only as an electrode for electrochemical supercapacitors because of its excellent specific capacitance, capacity retention rate, power density, and energy density, but also as a catalyst for decomposing harmful organic waste due to its excellent decomposition ability of organic matter.
