  • 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 ...
  • 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 ...
  • Three-dimensional ruthenium-doped TiO2 sea urchins for enhanced visible-light-responsive H-2 production 

    Thuy Duong, Nguyen-Phan; Luo, Si; Vovchok, Dimitriy; Llorca Piqué, Jordi; Sallis, Shawn; Kattel, Shyam; Xu, Wenqian; Piper, Louis F. J.; Poliansky, Dimitry E.; Senanayake, Sanjaya D.; Stacchiola, Darío J.; Rodriguez, Jose A. (2016-06-21)
    Article
    Open Access
    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 ...
