Abstract

The invention discloses a preparation method of a hollow porous TiO2 nanocubic material. The method firstly mixes titanium isopropoxide and methanol, adds into a mixture of 2-aminoterephthalic acid and N,N-dimethylformamide for a reaction, obtains an amino-modified Ti-MIL-125 nanocube material, conducts stirring for the reaction after water, sodium hydroxide and absolute ethanol are added, obtainsa nano-precursor material, and finally conducts heat-treating to obtain the hollow porous TiO2 nanocubic material; the invention discloses application of the hollow porous TiO2 nanocubic material ina lithium ion battery. The method utilizes the characteristics that acidic ligands constituting the amino-modified Ti-MIL-125 nanometer material are not stable under the alkaline condition to conductself-etching, thereby ensuring the stability of the structure and performance; the hollow porous TiO2 nanocubic material is applied to the lithium ion battery to increase the specific capacity of thelithium ion battery.
