The present invention relates to a highly efficient and versatile/broad spectrum decontamination sanitizing additive comprising metal oxide nanoparticles in a metal or semi-metal nanoparticle matrix, preferably in a metal or semi-metal nanocatalyst matrix, several types of common products that can be used to protect, coat or decorate surfaces, such as paints, varnishes, etc. The decontaminating and disinfecting additive is converted into a decontaminating and disinfecting product mainly based on the photocatalytic properties of the metal oxide nanoparticles, and is then able to remove/eliminate contaminants from the environment around outdoor or indoor surfaces to which the decontaminating and disinfecting additive is applied. The decontaminating and disinfecting additive can be prepared as a "ready-to-use" powder, a solution to be sprayed on a surface, or a formulation to be spread on a surface, and can also remove/eliminate contaminants, such as CO, CO2, NO, NO2, SO2, COV, methane, particulate matter, polyc
