Effects of thickness extension mode resonance oscillation of acoustic waves on catalytic and surface properties. 5. Effects of ferroelectric crystal thickness on the catalytic behavior of Ag for ethanol decomposition

Article Abstract:

Five kinds of ferroelectric z-cut LiNbO3 crystals with different thickness of 0.3, 0.5,1.0,2.0, and 2.2 nm were employed to reveal the effects of frequency in thickness extension mode resonance oscillation (TERO) of acoustic waves on the catalytic properties of a 100 nm thick Ag film deposited onto the crystals. The frequency effects of different crystal thickness on catalytic behavior are discussed.

Effect of Ag(super +) cations on nanooxidative activation of methane to C2-hydrocarbons

Article Abstract:

Ag/ZSM-5 catalysts were prepared by the conventional wetness impregnation method, and Ag(super +) was formed by the solid-phase reaction, which was confirmed by various characterization techniques. Ag(super +) ions were found to be the main Ag species at lot loading, and Ag metal clusters were formed at higher loading.

Ag(super +)-inserted NbO2F as a novel photocatalyst

Article Abstract:

The decomposition of gaseous 2-propanol (IPA) under 400-530 and 300-400 nm light irradiations are used to evaluate the photocatalytic activities of NbO2F and Ag-NbO2F. It is found that the Ag-NbO2F could decompose IPA to CO2 through acetone under both irradiation conditions.
