Abstract Silica-supported and alumina-supported platinum catalysts have been successfully prepared using the aerosol-gel method for hydrocarbon-based selective catalytic reduction of nitrogen mono-oxide. The Pt dots as small as 1-2 nm were well dispersed on silica and alumina spherical particles with large number of active surface. By flowing NO gas through the catalysts powder which was kept at different temperatures and measuring the composition of NO gas, steady-state catalytic de-NOx performance was tested as a function of temperature. Of particular interest is to note that the alumina-supported catalysts were more active even as low as 150 oC as compared to silica-based catalysts. The NO conversion efficiency reached 60% with wider temperature range.
