Abstract: A method of making a nanotube array structure includes forming a nanorod array template on a substrate, coating a nanotube material over the nanorod array template, forming a coated template, annealing the coated template, and drying the coated template. The method then includes heating the coated template to an elevated temperature, relative to ambient temperature, at a heating rate while flowing a gas mixture including a reducing gas over the substrate at a flow rate, the reducing gas reacting with the nanorod array template and forming a gaseous byproduct and the nanotube array structure in which nanotubes may be substantially aligned with adjacent nanotubes. The nanotube array structure can be used, for example, in sensor, catalyst, transistor, or solar cell applications.

Abstract: A metal oxide nanorod array structure according to embodiments disclosed herein includes a monolithic substrate having a surface and multiple channels, an interface layer bonded to the surface of the substrate, and a metal oxide nanorod array coupled to the substrate surface via the interface layer. The metal oxide can include ceria, zinc oxide, tin oxide, alumina, zirconia, cobalt oxide, and gallium oxide. The substrate can include a glass substrate, a plastic substrate, a silicon substrate, a ceramic monolith, and a stainless steel monolith. The ceramic can include cordierite, alumina, tin oxide, and titania. The nanorod array structure can include a perovskite shell, such as a lanthanum-based transition metal oxide, or a metal oxide shell, such as ceria, zinc oxide, tin oxide, alumina, zirconia, cobalt oxide, and gallium oxide, or a coating of metal particles, such as platinum, gold, palladium, rhodium, and ruthenium, over each metal oxide nanorod. Structures can be bonded to the surface of a substrate and resist erosion if exposed to high velocity flow rates.
