Abstract: Disclosed is a method for producing titanium dioxide powder and a method for producing a photocatalyst device using the same. The method for producing photocatalyst device comprises the steps of: obtaining a precipitate by hydrolyzing a titanium dioxide precursor solution and a solvent; adding acid components in a solution including the precipitate in order to be aged; obtaining wet titanium dioxide powder by centrifuging the aged solution; obtaining titanium dioxide powder having an average particle size of 15-25 nm by drying and pulverizing the wet titanium dioxide powder and firstly heating the dried titanium dioxide powder by increasing the temperature of the same at a particular speed; annealing the dried titanium dioxide powder at a temperature of 400-1100°C for 0.5-4 hours; producing a titanium dioxide photocatalyst layer by coating the surface of a quartz glass substrate with a dispersed solution obtained by dispersing the annealed titanium dioxide powder in Na2SiO3; and grouping quartz glass substrates on which titanium dioxide photocatalyst layers are formed and forming a multilayer structure in order to be connected with a UV lamp so that the photocatalyst device is produced.
