MANUFACTURING METHOD FOR TITANIUM DIOXIDE, AND PHOTOCATALYST APPARATUS CONTAINING TITANIUM DIOXIDE PHOTOCATALYST LAYER

摘要

The present invention relates to a manufacturing method for titanium dioxide comprising: a step of obtaining precipitates by hydrolyzing a titanium dioxide precursor solution; a step of adding acids to the solution containing the precipitates and aging them; a step of obtaining powders or thin films dried from the aged solution; a step of annealing the dried powder or thin films, and a photocatalyst apparatus containing titanium dioxide as a photocatalyst layer. In the present invention, the photocatalyst layer, in which the titanium dioxide thin film and powers are applied on the surface of a quartz glass of a disc type, is formed and connected to an ultraviolet lamp in a multilayered structure, thereby manufacturing the photocatalyst apparatus with a simple method. Additionally, the photocatalyst apparatus exhibits a photocatalyst effect which is equivalent to the existing products or is excellent as compared to the existing products.;COPYRIGHT KIPO 2014
