On the nature of active sites in MoVTeO and MoVTeNbO catalysts. The influence of catalyst activation temperature

Concepción Heydorn, Patricia; Hernández Morejudo, Selene; López Nieto, José Manuel (Elsevier, 2011-01-04)

[EN] MoVTeO and MoVTeNbO catalysts have been prepared, characterized (by XRD, Raman, IR. XPS, oxygen isotopic-exchange and IR of adsorbed methanol) and tested in the partial oxidation of propane to acrylic acid. The catalysts ...
Oxidative dehydrogenation of ethane over Ni-W-O mixed metal oxides catalysts

Solsona Espriu, Benjamin Eduardo; López Nieto, José Manuel; Concepción Heydorn, Patricia; Dejoz, A.; Ivars Barceló, Francisco; Vazquez, M. I. (Elsevier, 2011-05-16)

Ni-W-O mixed oxides were prepared through the evaporation of aqueous solutions of nickel nitrate and ammonium tungstate and calcined in air at 500 degrees C for 2 h. The catalysts were characterized by several techniques ...
Selective oxidation of ethane: Developing an orthorrombic phase in Mo-V-X (X=Nb,Sb,Te) mixed oxides

Botella Asuncion, Pablo; Dejoz, A.; Abello, M. C.; Vazquez, M. I.; Arrua, L.; López Nieto, José Manuel (Elsevier, 2009-04-30)

[EN] Mo-V-X (X = Nb, Sb and/or Te) mixed oxides have been prepared by hydrothermal synthesis and heat-treated in N(2) at 450 degrees C or 600 degrees C for 2 h. The calcination temperature and the presence or absence of ...
