  • 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 ...

    Three-dimensional (3D) monodispersed sea urchin-like Ru-doped rutile TiO2 hierarchical architectures composed of radially aligned, densely-packed TiO2 nanorods have been successfully synthesized via an acid-hydrothermal ...
  • 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 ...
