[0017] Add 10ml of absolute ethanol and 15ml of n-butyl titanate into a flat-bottomed flask and stir on a magnetic stirrer, then add 5ml of acetylacetone dropwise using a pipette, stir at room temperature for 10 minutes, and prepare solution A. Add 5ml of distilled water and 5ml of absolute ethanol into a 50ml beaker, then add 0.0234g of Fe(NO 3 ) 3 9H 2 O and 0.0186 g La(NO 3 ) 3 ·6H 2 O dubbed as Fe 3+ : La 3+ Solution B with a molar ratio of 1:1; an ion concentration of 0.02%. Put solution B in a constant pressure dropping funnel and drop it into solution A drop by drop, stir at high speed for 6h to obtain Fe 3+ , La 3+ Co-doped TiO2 alcohol sol. Dissolve PVAc in acetone to form a solution with a concentration of 15%. Put 40ml of the prepared alcohol sol into a constant pressure dropping funnel and drop it into 40ml of PVAc solution drop by drop, stir for 10 hours to make PVAc / TiO 2 Hybrid sol spinning solution. Put the spinning solution into self-made electrospi...
