[EN] Hydrothermally prepared Mo-V-Sb mixed oxides doped with alkali metal cations (Li+, Na+, K+, Rb+, or Cs+) show a significantly improved catalytic behavior in the oxidative dehydrogenation of ethane (ODH) compared to ...

[EN] The investigation here presented studies the effect of the synthesis temperature (from 80 to 110 degrees C) and the time (from 1 to 4 days) employed to precipitate catalyst precursors by reflux method, on the ...

SUMMARY The current doctoral thesis studies the synthesis of Mo-V-Te-containing mixed metal oxides and the characterization of their physico-chemical and catalytic properties for alkanes selective oxidation reactions, such ...

[EN] The robustness of one selected Ni-W-O catalyst has been studied in the oxidative dehydrogenation of ethane. This catalyst initially deactivates for the first 10 h online decreasing 15% of its catalytic activity compared ...

[EN] This work reports the applicability of reflux to the synthesis of Mo-V-Te-Nb-O metal oxide catalysts for the first time. The well-formed and defined orthorhombic M1 phase, i.e. Te2M20O57 (M = Mo, V, Nb), was found to ...

Nb-free (SbO)(2)M(20)O(56) catalysts (M = Mo, V) presenting pure M1 phase have been prepared by a post-synthesis treatment with hydrogen peroxide of a heat-treated MoVSbO mixed metal oxide catalyst previously prepared by ...

[EN] In the present article we show that, although the reflux method is not common for the synthesis of multicomponent MoVTeNbO catalysts, an optimized reflux synthesis of metallic precursors leads to efficient materials ...
