Phase assembly and electrical conductivity of spark plasma sintered CeO2–ZrO2 ceramics
(Springer Verlag, 2014)
Ce x Zr1−x O2 (x = 0.10, 0.16 and 0.33) nanocrystalline powders were obtained by a two-step synthesis technique and sintered by spark plasma sintering (SPS). As consequence of the reduction of Ce4+ to Ce3+ species by carbon ...

Could an efficient WGS catalyst be useful in the CO-PrOx reaction?
(Elsevier, 2014)
This work presents an evaluation of a high performance series of water gas shift (WGS) catalysts in the preferential CO oxidation reaction (PrOx) in order to examine the applicability of the same catalyst for both processes ...

Gold supported on CuOx/CeO2 catalyst for the purification of hydrogen by the CO preferential oxidation reaction (PROX)
(Elsevier, 2014)
Hydrogen produced from the conversion of hydrocarbons or alcohols contains variable amounts of CO that should be removed for some applications such as feeding low-temperature polymer electrolyte membrane fuel cells (PEMFCs). ...

Pt vs. Au in water-gas shift reaction
(Elsevier, 2014)
This work presents a comparison of the gold- and platinum-based catalysts behavior in the water-gas shift (WGS) reaction. The influence of the support, e.g., its composition and electronic properties, studied in detail by ...
