Abstract
The invention provides a nickel oxide-titanium dioxide nano composite material, belonging to the technical field of inorganic functional materials. The nano composite material is prepared by preparing a strip-shaped Na2Ti8O17 precursor from TiO2 serving as a basic raw material and a NaOH solution serving as a reaction solvent by using a hydrothermal method, then soaking, pickling and performing suction filtration to obtain strip-shaped H2Ti8O17, and putting the strip-shaped H2Ti8O17 into a muffle furnace for calcining for 2 hours so as to obtain a TiO2 nano strip; by taking urea, nickel nitrate, water and TiO2 as raw materials, keeping the temperature of 120 DEG C for 4-6 hours by using a homogeneous precipitation method, and then calcining for 2 hours at 400 DEG C so as to obtain a novel nickel oxide-titanium dioxide one-dimensional nano composite material which has the advantages of no toxicity, low cost, no pollution, high specific capacity, good security, good catalytic performance and the like, and has wide application prospects in fields such as lithium ion batteries, photocatalysis and the like.
Description
Technical field
The present invention relates to a kind of nickel oxide-titanic oxide nano compound material, belong to inorganic functional material field.
Background technology
Monodimension nanometer material refers in three dimensions of material have the size of two dimensions to drop on the novel nano-material between 1～100 nanometer, for example: nanotube, nano wire, nanometer rod, nano belt etc.Because one-dimensional material has physics unique compared with block materials and chemical property and obtained common people's extensive concern, in several years of the past, ZnO, SnO
