Abstract
Methods of removing odors, particularly odors within enclosed environments are provided which employ nanocrystalline metal oxide and metal hydroxide particles. The nanocrystalline particles are dispersed within an enclosed space so as to contact exposed surfaces located within the space such as walls, floors, upholstery, and the like and adsorb odor-causing materials located within the enclosed space.
