Combined in situ PM-IRRAS/QCM studies of water adsorption on plasma modified aluminum oxide/aluminum substrates

- Tailoring of oxyhydroxide aluminum surface chemistry by means of low-temperature plasma treatments.
- Water adsorption experiments on plasma modified surfaces followed by a new PM-IRRAS/QCM setup.
- Ultra-thin plasma formed oxide layer led to the accelerated growth of the atmospheric oxide layer.
- Negligible chemisorption process on the Ar/H2O-plasma modified surface upon exposure to humid air.
- High hydroxyl surface density led to a strongly surface bound water film at low relative humidities.
