Abstract

The invention discloses an In2O3 oriented growth structure, flower-like structure, dendritic structure, hollowed structure and tetrahedral structure along TiO2 nanofiber surfaces and a preparation method. The TiO2 nanofiber is prepared by the hydro-thermal synthesis method. The In2O3 is prepared by the magnetron sputtering technology. The In2O3 oriented growth, flower-like, dendritic, hollowed and tetrahedral structures are multistage and ordered, and are advantaged by high specific surface area, high permeability, good photocatalytic performance and conductivity.

Description

technical field [0001] The invention relates to a multi-level ordered In 2 o 3 structure, especially involving a TiO 2 Oriented growth structure, flower-like structure, dendritic structure, hollow-out structure, tetrahedral structure displayed on the surface of the nanofiber and a preparation method thereof. Background technique [0002] Dioxide (In 2 o 3 ) Indium is an extended product of indium, which is a frequently used raw material in resistive touch screens, mainly used in fluorescent screens, glass, ceramics, chemical reagents, etc. In addition, it is widely used in traditional fields such as colored glass, ceramics, mercury substitution for alkaline manganese batteries, and chemical reagents. In recent years, it has been widely used in high-tech fields such as the optoelectronic industry and military fields. It is especially suitable for processing into indium tin oxide (ITO) targets, manufacturing transparent electrodes and transparent heat reflector materials,...
