CuNi/Fe2O3 exhibited the highest CO conversion with negligible CH4 selectivity at the extremely high GHSV of 101 000 h(-1) (X-CO = 85% at 400 degrees C). The high activity of CuNi/Fe2O3 catalyst is mainly due to the increase in the lattice strain and the decrease in the binding energy of lattice oxygen. In addition, X-ray photoelectron spectroscopy (XPS) results provide direct evidence for the formation of surface CuNi alloy, which plays a critical role in suppressing the methanation reaction. The detailed characterization by powder X-ray diffraction (XRD), XPS, BET, and H-2 temperature-programmed reduction (TPR) techniques was used to understand the role of dopants on host iron oxides in the enhancement of catalytic activity for HT-WGS reaction.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Foreign&lt;/p&gt;</style></custom3><custom4><style face="normal" font="default" size="100%">5.287</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Jha, Ajay</style></author><author><style face="normal" font="default" size="100%">Jeong, Dae-Woon</style></author><author><style face="normal" font="default" size="100%">Lee, Yeol-Lim</style></author><author><style face="normal" font="default" size="100%">Jang, Won-Jun</style></author><author><style face="normal" font="default" size="100%">Shim, Jae-Oh</style></author><author><style face="normal" font="default" size="100%">Jeon, Kyung-Won</style></author><author><style face="normal" font="default" size="100%">Rode, Chandrashekhar V.</style></author><author><style face="normal" font="default" size="100%">Roh, Hyun-Seog</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Chromium free high temperature water-gas shift catalyst for the production of hydrogen from waste derived synthesis gas</style></title><secondary-title><style face="normal" font="default" size="100%">Applied Catalysis A-General</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CeO2</style></keyword><keyword><style  face="normal" font="default" size="100%">Co-Ni-CeO2</style></keyword><keyword><style  face="normal" font="default" size="100%">Lattice strain</style></keyword><keyword><style  face="normal" font="default" size="100%">oxygen vacancies</style></keyword><keyword><style  face="normal" font="default" size="100%">Water-gas shift</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">JUL</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER SCIENCE BV</style></publisher><pub-location><style face="normal" font="default" size="100%">PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS</style></pub-location><volume><style face="normal" font="default" size="100%">522</style></volume><pages><style face="normal" font="default" size="100%">21-31</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;A comparative study between monometallic (Me-CeO2, Me =Zn, Cu, Fe and Co) and Ni-doped bimetallic (Me-Ni-CeO2) catalysts has been performed in the high temperature water-gas shift (HT-WGS) reaction using waste derived synthesis gas. Experimental results revealed that Me-Ni-CeO2 exhibited higher catalytic performance than simple Me-CeO2 catalysts. Within the Me-Ni-CeO2 series, Co-Ni-CeO2 exhibited excellent and stable catalytic performance (CO conversion &amp;gt; 90%) at a very high GHSV of 143,000 h(-1). The existence of high&quot; concentration of Ce3+ ions and oxygen vacancies on the catalyst surface were responsible for the increased WGS activity of Co-Ni-CeO2. In addition, Co-Ni-CeO2 maintains a stable performance for 50 h. However, commercial Fe2O3-Cr2O3 catalyst showed a steep decline from their initial CO conversion values 15-10% within 5 h.

Interestingly, alkali metal promoted catalysts deactivated rapidly compared to alkaline earth metal promoted catalysts. Alkaline earth metal promoted catalysts showed relatively higher stability (&amp;gt;50 h) even at a very high gas hourly space velocity of 143,000 h(-1). X-ray diffraction (XRD) and transmission electron microscopy (TEM) results reveal that the higher stability of the alkaline earth metal promoted catalysts was due to the strong resistance to sintering, showing a relatively small crystallite size of metallic cobalt compared to the alkali metal promoted catalysts after WGS reaction.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">4.339</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Na, Hyun-Suk</style></author><author><style face="normal" font="default" size="100%">Shim, Jae-Oh</style></author><author><style face="normal" font="default" size="100%">Jang, Won-Jun</style></author><author><style face="normal" font="default" size="100%">Jeon, Kyung-Won</style></author><author><style face="normal" font="default" size="100%">Kim, Hak-Min</style></author><author><style face="normal" font="default" size="100%">Lee, Yeol-Lim</style></author><author><style face="normal" font="default" size="100%">Lee, Da-We</style></author><author><style face="normal" font="default" size="100%">Yoo, Seong-Yeun</style></author><author><style face="normal" font="default" size="100%">Bae, Jong Wook</style></author><author><style face="normal" font="default" size="100%">Rode, Chandrashekhar V.</style></author><author><style face="normal" font="default" size="100%">Roh, Hyun-Seog</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effect of titration time on the catalytic performance of Cu/CeO2 catalysts for water-gas shift reaction</style></title><secondary-title><style face="normal" font="default" size="100%">Catalysis Today</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">JUL</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">309</style></volume><pages><style face="normal" font="default" size="100%">83-88</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We herein report the preparation of ceria (CeO2) via a simple precipitation method for use as a catalyst support in the water-gas shift (WGS) reaction. More specifically, we optimized the titration time required to obtain highly active CeO2-supported catalysts for the WGS reaction. As such, Cu was employed as the active metal coupled with the CeO2 support. Notably, the CeO2-0 supported Cu catalyst (where the precipitant was immediately injected into a cerium nitrate solution) exhibited the highest CO conversion at a gas hourly space velocity of 36,050 h(-1). This high catalytic activity of the Cu/CeO2-0 catalyst was mainly due to its high Brunauer-Emmett-Teller (BET) surface area, enhanced Cu dispersion, high number of oxygen vacancies, and enhanced reducibility.</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">4.636</style></custom4></record></records></xml>
