Abstract: A vertical chemical vapor deposition (CVD) reactor and a method for synthesizing metal oxide impregnated carbon nanotubes. The CVD reactor includes a preheating zone portion and a reaction zone portion, and preferably an additional cooling zone portion and a product collector. The method includes (a) subjecting a liquid reactant solution comprising an organic solvent, a metallocene, and a metal alkoxide to atomization in the presence of a gas flow comprising a carrier gas and a support gas to form an atomized mixture, and (b) heating the atomized mixture to a temperature of 200° C.-1400° C., wherein the heating forms a metal oxide and at least one carbon source compound, wherein the metallocene catalyzes the formation of carbon nanotubes from the at least one carbon source compound and the metal oxide is incorporated into or on a surface of the carbon nanotubes to form the metal oxide impregnated carbon nanotubes.

Abstract: A process for making an iron oxide impregnated carbon nanotube membrane. In this template-free and binder-free process, iron oxide nanoparticles are homogeneously dispersed onto the surface of carbon nanotubes by wet impregnation. The amount of iron oxide nanoparticles loaded on the carbon nanotubes range from 0.25-80% by weight per total weight of the doped carbon nanotubes. The iron oxide doped carbon nanotubes are then pressed to form a carbon nanotube disc which is then sintered at high temperatures to form a mixed matrix membrane of iron oxide nanoparticles homogeneously dispersed across a carbon nanotube matrix. Methods of characterizing porosity, hydrophilicity and fouling potential of the carbon nanotube membrane are also described.
