Claim Text:
1. A method for fabricating a carbon nano-filter system for removing toxic pollutants and hydrocarbons, the method comprising the steps of: synthesizing and purifying single-walled or multi-walled carbon nanotubes; spraying palladium and rhodium nanoparticles on the surfaces of the carbon nanotubes, growing a plurality of non-metallic sensors on the nanotubes; coating the nanotubes with a hydrophobic layer of metal-metal oxide nanoparticles to form nano-catalyst structures having an increased surface area coefficient, drying the nano-catalyst structures at a temperature of 120° C.; mixing the dried nano-catalyst structures with a phenolic binder resin to form catalytic nanoparticles; coating an interior surface of a plurality of monolithic structures with the catalytic nanoparticles; calcining the coated monolithic structures in a vacuum furnace; cooling the calcined monolithic structures; and spraying a solution on the interior surface of calcined monolithic structures to coat the interior surface of the calcined structures with metal-metal oxide nanoparticles, wherein the solution comprises 5.2 grams of ammonium heptamolybdate and 4.3 grams of cobalt nitrate in 47.4 grams of distilled water, wherein the metal-metal oxide nanoparticles comprise cobalt oxide, palladium and molybdenum oxide, and wherein the cobalt oxide is derived from the cobalt nitrate and wherein the molybdenum is derived from the ammonium heptamolybdate.
