Effect of support composition on the origin and reactivity of carbon formed during dry reforming of methane over 5 wt% Ni/Ce1-xMxO2-δ (M = Zr4+, Pr3+) catalysts
(2016)Carbon dioxide reforming of methane to synthesis gas in the 550-750°C range over 5 wt% Ni/Ce1-xMxO2-δ (M = Zr4+, Pr3+) solids has been investigated with respect to the effects of support chemical composition and reaction ...

Origin and reactivity of active and inactive carbon formed during DRM over Ni/Ce0.38Zr0.62O2-δ studied by transient isotopic techniques
(2016)The role of Ce0.38Zr0.62O2-δ redox support and that of reactants CH4 and CO2 in the carbon-path of dry reforming of methane (DRM) at 750°C over a 3wt% Ni/Ce0.38Zr0.62O2-δ catalyst were investigated. In particular, meticulously ...

Partially yttria-stabilized zirconia coatings produced under plasma-assisted EBPVD with bipolar pulsed bias and under electron bombardment-assisted positive bias conditions
(1997)Previous research using radio frequency (rf) plasma-assisted electron beam (EB) PVD to deposit partially yttria-stabilized zirconia (PYSZ) thermal barrier coatings has shown the benefits of this method in terms of structure ...

Selective catalytic reduction of NO by H2/C3H6 over Pt/Ce1-xZrxO2-Δ: The synergy effect studied by transient techniques
(2017)A series of Pt/CexZr1-xO2-δ(x = 0.4–0.6) solids were synthesized and evaluated for the SCR of NO under lean burn conditions (2.5 vol% O2) using C3H6and H2as reducing agents. SSITKA-Mass Spectrometry, SSITKA-DRIFTS and other ...

Suppression of the oxygen storage and release kinetics in Ce0.5Zr0.5O2 induced by P, Ca and Zn chemical poisoning
(2011)The present investigation concerns for the first time the understanding of the individual and combined effects of phosphorous with calcium or zinc deposited on a Ce0.5Zr0.5O2 solid followed by calcination in 20%O2/He at ...
