    摘要: Nitrogen-doped titania nanotubes exhibiting catalytic activity on exposure to any one or more of ultraviolet, visible, and/or infrared radiation, or combinations thereof are disclosed. The nanotube arrays may be co-doped with one or more nonmetals and may further include co-catalyst nanoparticles. Also, methods are disclosed for use of nitrogen-doped titania nanotubes in catalytic conversion of carbon dioxide alone or in admixture with hydrogen-containing gases such as water vapor and/or other reactants as may be present or desirable into products such as hydrocarbons and hydrocarbon-containing products, hydrogen and hydrogen-containing products, carbon monoxide and other carbon-containing products, or combinations thereof.

    摘要: A catalyst material for carbon nanotube synthesis includes a uniform dispersion of host particles on a substrate. The host particles themselves include catalyst nanoparticles that are effective to catalyze nanotube syntheses reactions and provide nucleation sites. Methods for preparing catalyst materials include co-sputtering a catalytic species and a host species to form a precursor thin film on a substrate, followed by an oxidation reaction of the precursor thin film in air. The precursor thin film can be patterned on the substrate to limit the locations of the catalyst material to well-defined areas. Methods for nanotube synthesis employ CVD in conjunction with the catalyst materials of the invention. During the synthesis, the catalyst nanoparticles catalyze carbon nanotubes to grown from a carbon-containing gas.

    摘要: A method for applying a carbon nanotube growth catalyst to at least one specified location on a substrate surface of a substrate formed of conductive material, and the method includes a preparation step for preparing on the substrate a coating layer having a hole contacting the substrate surface at a location corresponding to the specified location. The method also includes a deposition step for forming by deposition a conical deposited material on a substrate surface portion contacting the hole by irradiating the substrate with electrically conductive material particles in a oblique direction from above the coating layer while rotating the substrate about a shaft perpendicular to the substrate surface, and for forming by deposition an eaves-like deposited layer which extends to close an opening of the hole. The method also includes a determination step for measuring a size of the opening in accordance with extension of the eaves-like deposited layer, and a catalyst applying step for applying the catalyst to a tip of the conical deposited material by way of irradiation of material particles of the catalyst via the opening when the opening is measured to have a specified size.
