Described is related to nano-structured composite materials for removing harmful chemical air pollutants and odors from the air to prevent people from breathing in disease-causing chemicals and provide them with clean indoor air. The nano-structured composite materials comprise nano-catalysts embedded in the pores of nano-structured substrate materials selected from the group consisting of nano-porous carbon, nano-porous rare earth oxide, nano-porous zeolite, nano-porous alumina and nano-porous silica. The nano-scale synergy of nano-catalysts and nano-structured substrate materials provides effective air filtration materials for the complete trapping and elimination of the full spectrum of chemical air pollutants including both organic and inorganic compounds and odors for indoor spaces, which HEPA or activated carbon filters cannot achieve.
