Cu/MnOx–CeO2 and Ni/MnOx–CeO2 catalysts for the water–gas shift reaction: Metal–support interaction

Hydrogen production from water–gas shift reaction over Ni–Cu–CeO 2 oxide catalyst: The effect of preparation methods

“…In WGS reaction, the main reaction barrier is the splitting of water which is very high for Cu-based catalysts [13]. Ni-is more reactive toward H 2 O than Cu in the WGS reaction [14]. Introduction of Ni-to the Cu-based catalysts may lower the barrier for water splitting and ultimately accelerate the WGS reaction [15].…”

Role of the Interface in Base‐Metal Ceria‐Based Catalysts for Hydrogen Purification and Production Processes

“…Other oxide‐type interfacial entities appeared by evolution of fluorite‐type ceria binary, and ternary phases or from multicationic perovskite structures . We can also mention the decomposition of NiTiO 3 under the reaction conditions to render Ni and TiO 2 at CeO 2 surfaces as a close system, but in which M‐CeO 2 contact is of relatively low importance in comparison with the M‐TiO 2 contact …”

“…In the case of fluorite‐type ceria binary mixed oxides with Mn, the evolution under the reaction conditions generates Cu x Mn y O z spinel and NiMnO 3 structures as detected by using ex situ XRD. Therefore, in both cases, for Cu‐ and Ni‐based catalysts, an intimate contact (shown ex situ, but likely present in the reaction) between the metal and Mn provides high activity in the WGS reaction with the depression of the methanation activity in the case of Ni …”

Catalytic nonthermal plasma assisted co-processing of methane and nitrous oxide for methanol production

“…Free radical mechanism in NTP is widely accepted [33,38,40,41]. NTP generates energetic electrons and excited species that react with CH 4 and N 2 O to generate free radicals or neutrals, positive ions, negative ions, and excited molecules.…”

“…Another interesting aspect is that addition of catalyst to the plasma reactor also improved the activity http://dx.doi.org/10.1016/j.cattod.2015.03.011 0920-5861/© 2015 Elsevier B.V. All rights reserved. and selectivity [26][27][28][29][30][31][32][33]. With this background, present study deals with NTP assisted co-processing of nitrous oxide (N 2 O) and methane (CH 4 ) aiming at methanol production.…”
