The mechanism of CO oxidation with O2 on Ag-contaminated Au fine powder (Ag/Au) was studied by kinetic measurements combined with the determination of the amount of CO2 produced. The kinetic behavior of “Ag/Au having the steady state surfaces” in

We investigated Au catalysts supported on TiO2, Fe2O3, and ZnO for their preferential oxidation of CO in a H2-rich atmosphere. Both full conversion and selectivity were achieved over Au/Fe2O3 and Au/ZnO around room temperature, but at higher temperat

We have found a new route for preparing Pt containing perovskites. Ba containing perovskite powder, (La0.7Sr0.2Ba0.1)ScO3–δ (LSBS), reacted with Pt foil at 1898 K in air, and formed ultramarine colored Pt containing perovskite, (La0.7Sr0.2Ba0.1)(S

In this work, a nonthermal plasma was applied to the TiO 2 -supported gold nanoparticle catalysts (Au/TiO 2 ) for the catalyst regeneration and the enhancement of catalytic activity for CO oxidation. Exposure to the 100 ppm toluene or C 3 H 6 resulte

It has been found that Pt eluted into the (La0.7Sr0.2Ba0.1)ScO3-δ perovskite oxide exhibited higher catalytic activity for CO oxidation than for H2 oxidation under separate reaction conditions, a behaviour which differs from that of conventional Pt

In situ FT-IR measurements for Au/TiO 2 and Au/Al 2 O 3 have been carried out under the flow condition of CO oxidation at atmospheric pressure. It has been found that the Au particles remain neutral (Au°) in the presence of oxygen, while negatively

We have prepared titania aerogel and titania-coated silica aerogel incorporating Au nanoparticles. While the sizes of the Au particles in the titania aerogel considerably increased upon calcination at 673 K, those in the titania-coated silica aerogel
