NOVELTY - Tetrabutyl titanate and polyvinylpyrrolidone are dissolved in organic solvent, to obtain uniform core layer spinning liquid. 0.4-0.8 %Mass tin tetrachloride pentahydrate, indium trichloride and polyvinylpyrrolidone are dissolved in organic solvent, to obtain uniform shell spinning liquid. The uniform core layer spinning liquid and uniform shell spinning liquid in ratio of 0.5:1, are fed into an electrospinning apparatus, coaxial electrospinning process is performed and calcined, to obtain indium-tin oxide fibers integrally covered with titanium oxide structure.    USE - Preparation of indium-tin oxide-coated titanium oxide nanofibers used for solar cell, nanofiber device and sensor material.    ADVANTAGE - The method provides indium-tin oxide-coated titanium oxide nanofibers having continuous fiber structure, small fiber diameter and high specific surface area.    DETAILED DESCRIPTION - Tetrabutyl titanate and 10 %mass polyvinylpyrrolidone are dissolved in organic solvent and mixed uniformly, to obtain uniform core layer spinning liquid. 0.4-0.8 %Mass tin tetrachloride pentahydrate, 0.2-0.5 %mass indium trichloride and polyvinylpyrrolidone are dissolved in organic solvent and stirred, to obtain uniform shell spinning liquid. The uniform core layer spinning liquid and uniform shell spinning liquid in ratio of 0.5:1, are fed into an electrospinning apparatus, coaxial electrospinning process is performed at 10-20 kV and 1-4 mL/hour, to obtain nonwoven fabric-like fibrous felt and calcined in a muffle furnace at 600-100 degrees C for 5 hours at heating rate of 3-8 degrees C/minutes, to obtain indium-tin oxide fibers integrally covered with titanium oxide structure. The organic solvent is mixture of ethylene glycol, glycerol and n-butanol in mass ratio of 1:1:1. The volume ratio of organic solvent and tetrabutyl titanate is 20:5-15. The volume ratio of tin tetrachloride pentahydrate and indium trichloride is 10:2-5. The indium-tin oxide-coated titanium oxide nanofibers have average diameter of 80-400 nm, and comprises 20-80 %mass titanium oxide and indium-tin oxide.
