Abstract

The invention discloses a nickel oxide/copper oxide composite nanomaterial with a hollow sphere structure and a preparation method of the nickel oxide/copper oxide composite nanomaterial. The preparation method comprises steps as follows: nickel salt and bivalent copper salt are dissolved in a solvent, a mixed solution is obtained, a polymer-supported reagent and urea are added to the mixed solution in sequence and stirred until the polymer-supported reagent and urea are dissolved completely, then a mixture is subjected to a hydrothermal reaction, an obtained product is further calcined, and the nickel oxide/copper oxide composite nanomaterial with the hollow sphere structure is obtained after calcination. Compared with the prior art, the raw materials are cheap and available, a template is not required to be added to a reaction system for obtaining of the hollow structure, the synthesis process is simple, the obtained product is controllable in structure and size, and product yield ishigh.
