      Structuring Pt/CeO2/Al2O3 WGS catalyst: Introduction of buffer layer  [Article]

      González Castaño, Míriam; Ivanova, Svetlana; Laguna Espitia, Oscar Hernando; Martínez Tejada, Leidy Marcela; Centeno Gallego, Miguel Ángel; Odriozola Gordón, José Antonio (Elsevier, 2016)
      This work is devoted to the development of novel structured catalytic system for WGS reaction. The new concept is related to the presence of a pre-catalytic “buffer” layer formed by WGS-inert oxide, i.e. not involved in ...
