1. A catalyst composition that converts nitrogen oxides in exhaust streams generated by combustion of fossil fuels, comprising:
a homogeneous solid mixture having ordered directionally aligned tubular meso-channel pores having an average diameter in a range of about 1 nanometer to about 15 nanometers, wherein the homogeneous solid mixture is comprised of (i) at least one catalytic metal and (ii) at least one metal inorganic network; wherein the metal inorganic network is a metal carbide, nitride, hydroxide, carbonitride, oxynitride, boride, and/or borocarbide, or a metal oxide, wherein the metal in the metal inorganic network is one or more of aluminum, titanium, zirconium, manganese, zinc, iron, calcium, and/or manganese and excluding silicon and cerium; and wherein the directionally aligned tubular meso-channel pores are formed by preparing the homogeneous solid mixture from a gel formed in the presence of a solvent, modifier, an inorganic halide, sulfate, nitrate, and/or sulfide salt precursor of the catalytic metal, an inorganic precursor of the metal inorganic network, and a templating agent, wherein the templating agent comprises an octylphenol ethoxylate having a structure [I]wherein “n” is an integer having a value of about 8 to 20. |
