Abstract
The present teachings are directed toward hexagonally patterned porous titania synthesized from a titanium isopropoxide precursor using a viscous template of surface-active agents separating nanoscopic bicontinuous channels of water and isooctane. Subsequent catalyst metal salt reduction in the aqueous nanochannels deposits well-separated catalyst metal nanoparticles on the pore surfaces. These nanocomposites exhibit significantly higher carbon monoxide oxidation efficiency than that obtained with known supports with higher specific surface area; efficiency is believed to be due to decreased mass transfer resistance provided the presently disclosed support material.
