Adsorption of water on graphene/Ru(0001)—an experimental ultra-high vacuum study†
Abstract
Data for water adsorption on epitaxial graphene grown on Ru(0001) at ultra-high vacuum (clean conditions) are discussed. Accordingly, water adsorption was not affected by the support. The interaction is not strictly hydrophobic. We propose simple rules based on ultra-high vacuum kinetics to classify the water–graphene-support interactions.
