Samenvatting

Catalyst supports of CeO ₂ /SiO ₂ and Al ₂ O ₃ with three-dimensionally ordered macroporous structure were fabricated in microchannels by application of PMMA opals as templates. Pt-Rh supported on CeO ₂ /SiO ₂ showed high efficiency for CO removal in preferential CO oxidation in the presence of excess hydrogen. Pt-Rh supported on Al ₂ O ₃ with an inverse opal structure showed higher reactivity than that supported on wash-coated Al ₂ O ₃ layers in microchannel reactor.
