  • Cu supported on mesoporous ceria: water gas shift activity at low Cu loadings through metal-support interactions 

    Vovchock, Dimitriy; Guild, Curtis J.; Llorca Piqué, Jordi; Xu, Wenqian; Jafari, Tahereh; Toloueinia, Panteha; Kriz, David A.; Palomino, Robert M.; Waluyo, Iradwikanari; Rodriguez, Jose A.; Suib, Steven L.; Senanayake, S. D. (2017-06-20)
    Article
    Open Access
    We have synthesized and tested a highly active Cu doped mesoporous CeO2 catalyst system for the low temperature water-gas shift (WGS) reaction. While typical oxide-supported copper WGS catalysts are characterized by high ...
  • In situ characterization of mesoporous Co/CeO2 catalysts for the high-temperature water-gas shift 

    Vovchock, Dimitriy; Guild, Curtis J.; Dissanayake, Shanka; Llorca Piqué, Jordi; Stavitski, Eli; Liu, Yongyuan; Palomino, Robert M.; Waluyo, Iradwikanari; Li, YuanYuan; Frenkel, Anatoly I.; Rodriguez, José A.; Suib, Steven L.; Senanayake, S. D. (2018-04-26)
    Article
    Open Access
    Mesoporous Co/CeO2 catalysts were found to exhibit significant activity for the high-temperature water-gas shift (WGS) reaction with cobalt loadings as low as 1 wt %. The catalysts feature a uniform dispersion of cobalt ...
  • Structural and chemical state of doped and impregnated mesoporous Ni/CeO2 catalysts for the water-gas shift 

    Vovchock, Dimitriy; Guild, Curtis J.; Llorca Piqué, Jordi; Palomino, Robert M.; Waluyo, Iradwikanari; Rodriguez, Jose A.; Suib, Steven L.; Senanayake, Sanjaya D. (2018-10-25)
    Article
    Restricted access - publisher's policy
    Mesoporous Ni/CeO2 catalysts of variable loadings were prepared using in-situ doping and impregnation synthesis techniques. The catalysts were found to exhibit activity for the water-gas shift (WGS) reaction, particularly ...
  • Water-gas-shift over metal-free nanocrystalline ceria: an experimental and theoretical study 

    Guild, Curtis J.; Vovchok, Dimitriy; Kriz, David A.; Bruix, Albert; Hammer, Bjork; Llorca Piqué, Jordi; Xu, Wenquian; El-Sawy, Abdelhamid; Biswas, Sourav; Rodriguez, Jose A.; Senanayake, S. D; Suib, Steven L. (2017-04-21)
    Article
    Open Access
    A tandem experimental and theoretical investigation of a mesoporous ceria catalyst reveals the properties of the metal oxide are conducive for activity typically ascribed to metals, suggesting reduced Ce3+ and oxygen ...
