Abstract
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.
