WebDec 29, 2015 · Silicon is one of many materials whose surface will oxidize in ambient conditions. However it is one of few materials whose native oxide will self-limit its growth in a matter of hours at a thickness of ∼2 nm. In this work, we show through the theory of repulsive van der Waals forces that this self-limitation is due, at least in part, to the … WebAug 20, 2012 · Complete oxidation of CO, ethanol, and ethyl acetate over copper oxide supported on titania and ceria modified titania P.
