Embodiment Construction

[0019] Exemplary embodiments will be described in more detail below with reference to the accompanying drawings. However, the invention may have different implementation forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this specification will be thorough and complete and will fully convey the spirit of the invention to those skilled in the art.

[0020] The technology disclosed in this document can be used to provide a photocatalytic filter in which the titanium dioxide photocatalyst has improved absorption for acetaldehyde, ammonia and acetic acid gas mixtures by introducing metals into the filter. An exemplary method for fabricating a photocatalytic filter with improved absorption of acetaldehyde, ammonia, and acetic acid gas mixtures includes the steps of: A photocatalytic dispersion liquid is provided, a photocatalytic support is coated with the photocatalytic dispersion liquid, the coated pho...

Abstract

The present disclosure relates to a photo-catalytic filter, the surface of which has enhanced adsorption performance so that mixed gases including a gas that reacts later in a competitive reaction can be degraded from the initial stage of a photo-catalytic reaction, and to a manufacturing method thereof. The method includes: dispersing carbon dioxide (TiO2) nano powder as a photo-catalyst and one or more metal compounds in water to prepare a photo-catalytic dispersion; coating a support with the photo-catalytic dispersion; drying the coated support; and sintering the dried support. The photo-catalytic filter includes a support, and a photo-catalyst and one or more metal compounds, which are coated on the support.

Description

[0001] This application is a divisional application of an invention patent application with an application date of March 4, 2015, an application number of 201510096590.7, and an invention title of "a photocatalytic filter for degrading mixed gases and its manufacturing method". technical field [0002] The present invention relates to a photocatalytic filter and a manufacturing method thereof, and more particularly to a filter whose surface has enhanced absorption properties so that a mixed gas containing a gas reacting later in a competing reaction can be degraded from the initial stage of a photocatalytic reaction Photocatalytic filter, and method for its manufacture. Background technique [0003] In this paper, the term "photocatalytic reaction" refers to the use of materials such as titanium oxide (TiO 2 ) or similar photocatalytic material reaction. Known photocatalytic reactions include photocatalytic degradation of water, electrodeposition of silver and platinum, deg...
