Abstract

The invention provides photocatalytic ceramic glaze as well as a preparation method and application thereof. The photocatalytic ceramic glaze is prepared from the following raw materials: a base material, a carbon material, a photocatalytic material and an infrared conversion material. The infrared conversion material can convert infrared light into ultraviolet light, so that the photocatalytic material can still realize a photocatalytic function under the condition of less visible light; and the photocatalytic ceramic glaze is convenient to treat nitrogen oxides, and is particularly suitable for the interior of a chimney.

Description

technical field [0001] The invention belongs to the technical field of materials and relates to a ceramic glaze, in particular to a photocatalyzed ceramic glaze and its preparation method and application. Background technique [0002] Air purification has a very important impact on human health. The quality of air directly affects people's work and life. The pathogenic substances contained in the air will cause serious harm to the human body. Although activated carbon and other harmful substances in the air can be adsorbed to a certain extent, they require special equipment and sites. Moreover, desorption treatment needs to be carried out in time after the adsorption is saturated, and the convenience of its application is not good. [0003] Photocatalysis mainly uses semiconductor oxide materials as catalysts. After receiving photon irradiation with energy greater than the forbidden band width, photo-generated electrons and photo-generated holes are generated under the activ...
