Abstract

The invention discloses a multi-groove photocatalyst ceramic plate. The multi-groove photocatalyst ceramic plate comprise a multi-groove ceramic plate; the internal part of the multi-groove ceramic plate is of a three-dimensional network structure; the surface of the multi-groove ceramic plate is provided with a plurality of grooves; the surface of the multi-groove ceramic plate is provided with a nanometer titanium dioxide photocatalyst material layer; metal particles are embedded into the surface of the nanometer titanium dioxide photocatalyst material layer. A preparation method comprises following steps: 1, the multi-groove ceramic plate is prepared; 2, a photocatalyst solution is prepared; 3, the multi-groove photocatalyst ceramic plate is prepared; and 4, the metal particles are added. The preparation method is simple; and the reaction capacity of the photocatalyst can be improved greatly by the metal particles embedded into the surface of the nanometer titanium dioxide photocatalyst material layer.

Description

technical field [0001] The invention relates to the technical field of ceramic plates, in particular to a porous photocatalyst ceramic plate. Background technique [0002] Currently, activated carbon filters are used for deodorization, but this method only physically absorbs odorous substances on the surface of the activated carbon filter. In this way, not only will it be affected by the environment such as temperature and humidity, but it may also release the absorbed odor and peculiar smell. Due to the limited absorption capacity of the activated carbon filter, it needs to be replaced in time when the absorption capacity is saturated, which will increase the burden of cost. [0003] With chemical sorbents, chemicals are used. The sorbent of chemical formula is to convert harmful gas into harmless by redox reaction. However, due to the use of medicines, they are used as consumables and must be replaced regularly, resulting in high costs. Chemicals cannot be treated as g...
