Lignocellulosic-derived mesoporous materials: an answer to manufacturing non-expensive catalysts useful for the biorefinery processes

Guerrero-Perez, M. O.; Valero-Romero, M. J.; Hernández Morejudo, Selene; López Nieto, José Manuel; Rodriguez-Mirasol, J.; Cordero, T. (Elsevier, 2012-11-15)

The synthesis procedure and characterization of a mesoporous carbon obtained from biomass waste by a simple method, generating a low-cost material, with the corresponding waste revaluation are described. The use of phosphoric ...
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 NiO-CeO2 mixed oxides catalysts

Solsona Espriu, Benjamin Eduardo; Concepción Heydorn, Patricia; Hernández Morejudo, Selene; Demicol, Benjamin; López Nieto, José Manuel (Elsevier, 2012-01-17)

[EN] In this paper we present the synthesis, characterization and catalytic behaviour in the oxidative dehydrogenation of ethane of NiO-CeO2 mixed oxides. The addition of cerium oxide to NiO strongly modifies its catalytic ...
Preparation, characterization and catalytic behavior for propanepartial oxidation of Ga-promoted MoVTeO catalysts

Hernández Morejudo, Selene; Massó Ramírez, Amada; García-González, Esther; Concepción Heydorn, Patricia; López Nieto, José Manuel (Elsevier, 2015-09-05)

[EN] Two sets of Ga-promoted MoVTeO catalysts were synthesized hydrothermally and heat-treated at 600 degrees C in N-2: (i) materials prepared from gels with Mo/V/Te/Ga atomic ratios of 1/0.60/0.17/x (x=0-0.12) (A-series) ...
