TITANIA NANOTUBE ARRAYS, METHODS OF MANUFACTURE AND PHOTOCATALYTIC CONVERSION OF CARBON DIOXIDE USING SAME

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 non -metals 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.
