Title:
HYDROGEN-DOPED REDUCED TITANIA POWDER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/219397
Kind Code:
A1
Abstract:
A preparation method for hydrogen-doped reduced titania (TiO2-x) powder of the present invention comprises: a mixture preparation step for mixing TiO2 particles, hydrides, and mixed salts; a crystallization step for preparing a crystallized product by reacting a mixture at a temperature higher than or equal to the eutectic melting point of the mixed salts; and a powder acquisition step for acquiring TiO2-x powder (in the formula, X is a rational number between 0.00001 and 2) from the crystallized product.
