Abstract: Metal oxide nanoarrays, such as titanium oxide nanoarrays, having a platinum group metal dispersed thereon and methods of making such nanoarrays are described. The platinum group metal can be dispersed on the metal oxide nanoarray as single atoms. The nanoarrays can be used to catalyze oxidation of combustion exhaust.

Abstract: A method of making a titanium dioxide nanowire array includes contacting a substrate with a solvent comprising a titanium (III) precursor, an acid, and an oxidant while microwave heating the solvent, thereby forming a hydrogen titanate H2Ti2O5.H2O nanowire array. The hydrogen titanate nanowire array is annealed to form a titanium dioxide nanowire array. The substrate is seeded with titanium dioxide before starting the hydrothermal synthesis of the hydrogen titanate nanowire array. The titanium dioxide nanowire array is loaded with a platinum group metal to form an exhaust gas catalyst. The titanium dioxide nanowire array can be used to catalyze oxidation of combustion exhaust.
