Low Temperature Oxidation of Trace Ethylene over Pt Nanoparticles Supported on Hydrophobic Mesoporous Silica
Hydrophobic SBA-15 has been found to improve catalytic activity of supported Pt nanoparticles for ethylene oxidation at 0 degrees C. Pt nanoparticles stabilized inside the hydrophobic mesopores enabled smooth ethylene conversion and CO2 formation at a steady state due to constant removal of physisorbed water formed during ethylene oxidation.
