Methods of reducing smoke levels in smoke-affected areas, reducing the level of toxic compounds produced by fires, fire suppression, and increasing flame retardancy. In particular, methods according to the present invention comprise dispersing nanocrystalline particles in the areas affected by smoke for sorption of smoke particulates and toxic compounds produced from a fire. The nanocrystalline particles are also effective for use in methods of fire suppression and flame retardancy.

Metal oxide nanoparticles for smoke clearing and fire suppression

Compositions and methods for destroying biological agents and toxins such as Aflatoxins, Botulinum toxins, and toxins are provided wherein the substance to be destroyed is contacted with a finely divided metal oxide nanocrystals. In various embodiments, the metal oxide nanocrystals have reactive atoms stabilized on their surfaces, species adsorbed on their surfaces, or are coated with a second metal oxide. The desired metal oxide nanocrystals can be pressed into pellets for use when a powder is not feasible. The methods of the invention are safe for humans, equipment, and the environment, and provide for decontamination of warfare sites, of equipment exposed to the contaminant, and of soil, water and air having been exposed to the contaminant. Preferred metal oxides for the methods include MgO, CaO, TiO , ZrO , FeO, V O , Mn O , Fe O , NiO, CuO, Al O , ZnO and mixtures thereof. Preferred reactive atoms stabilized on the surfaces of the metal oxide nanocrystals include halogens and Group I metals, and preferred species stabilized on the surfaces of the metal oxide nanocrystals include SO , NO and ozone.
