Abstract: The present invention is related to a high-efficient and versatile/broad-spectrum decontaminant and disinfectant additive comprising metal oxide nanoparticles in a metallic or semi-metallic nanoparticle matrix, preferably, in a metallic or semi-metallic nanocatalyst matrix, being able to convert several types of common products used for protecting, coating or decorating surfaces, such as paints, varnishes, or the like, into decontaminant and disinfectant products mainly based on the metal oxide nanoparticle photocatalytic properties, and then, being able of removing/eliminating contaminants from an environment around outdoor or indoor surfaces on which the same is applied. It can be prepared as a powder "ready-to-use", a solution to be sprayed or a formulation to be spread on a surface, and also can remove/eliminate contaminants such as CO, CO2, NO, NO2, SO2, COVs, methane, particulate material, polycyclic aromatic compounds, methylene chloride, chlorofluorocarbons (CFCs), virus, bacteria, molds, water-soluble organic contaminants or organic contaminant dispersions or suspensions, among others.

Abstract: The invention refers to an additive for ceramic glazes, ceramic glaze, to an activation method and process for producing the additive. The additive is composed of particles of semiconductor metal oxides of the Ti0 2 or ZnO type, doped in a proportion between 0.7 and up to 4.5 parts by weight, based on the total weight of the semiconductor metal oxide, with ions of Ag, or Cu, Au, Ni, Fe, Cr, Co, Mn, or combinations thereof. The composition comprises feldspar, sand, dolomite, alkali and / or alkaline earth oxides, borax to which is added, in mass ratio, between 3 to 20 parts of additive. The composition is used for glazing the surface of ceramic products, sanitary faience objects and the surface of ceramic tiles. It is presented a photocatalytic method of activating the photocatalytic additive in order to initiate the biocidal and disinfectant action, by irradiating the ceramic glaze with radiation in the visible domain having wavelengths between 450 nm şi 550 nm. There is also presented a process for obtaining an additive for ceramic glazes.
