On the deactivation of supported platinum catalysts for selective oxidation of alcohols

- Pt deactivated during alcohol oxidation because of strongly adsorbing species.
- Oxidized Pt was reduced by alcohol in an inert atmosphere.
- CO was observed by ATR-IR spectroscopy on Pt after alcohol adsorption.
- Aqueous O2 rapidly oxidized CO on the Pt surface.
- H2 treatment more effectively regenerated deactivated Pt than He treatment.
