The non-equilibrium electric discharge activated both the surface-oxygen and the lattice-oxygen of the oxides and methane molecules in the gas phase.
The above catalytic behavior was rationalized on the basis of different interactions occurring among gold, iron oxide and cerium oxide, which synergically affects both the reactivity of the surface oxygen and the capacity of the support to adsorb the organic reactant.
In a certain range of temperature and gas composition sustained oscillatory phenomena were observed on both the reaction rate and the surface oxygen activity.
In both configurations the bond length to the surface oxygen atom is larger than for a Ag adatom.
Both anodic and cathodic treatments lead to an increase in the surface oxygen groups.
The surface oxygen functional groups within OCG are favorable for high energy storage when applied as both battery-type negative electrodes and capacitor-type positive electrodes.
Beneath the surface, oxygen consumption through biological decay may cause serious depletion.
The inset presents the surface oxygen content as a function of RH.
In addition, the surface oxygen on the Cu surface may have existed as indicated by the EDS of the nanoparticle.
The surface oxygen content related to soot oxidation reactivity.
