  • 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 ...
  • In situ elucidation of the active state of Co-CeOx catalysts in the dry reforming of methane: the important role of the reducible oxide support and interactions with cobalt 

    Zhang, Feng; Liu, Zongyuan; Zhang, Shuhao; Akter, Nusnin; Palomino, Robert M.; Vovchok, Dimitriy; Orozco, Ivan; Salazar, David; Rodriguez, José A.; Llorca Piqué, Jordi; Lee, Jaeha; Kim, DoHeui; Xu, Wenqian; Frenkel, Anatoly I.; Li, Yuangyuang; Kim, Taejin; Senanayake, S. D. (2018-04-01)
    Article
    Open Access
    The dry reforming of methane was systematically studied over a series (2-30 wt%) of Co (~5nm in size) loaded CeO2 catalysts, with an effort to elucidate the behavior of Co and ceria in the catalytic process using in-situ ...
  • 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 ...
