“…This catalyst mostly used in the oxidative dehydrogenation of ethane and propane [24,25]. The catalytic behaviour of this catalyst also investigated for the ammoxidation of propane to acrylonitrile [26][27][28]. The catalyst structure and catalytic properties of Mo-VNb catalyst also investigated for selective oxidation of propane to acrylic acid [29][30][31].…”

In this paper, we report for the first time a one-pot reaction enabling total transformation of lactic acid to acetic acid over a Mo-V-Nb mixed oxide catalyst having an optimal atomic ratio 19:5:1. The mechanism of the reaction consists in two parallel ways leading to acetic acid: (i) oxi-dehydrogenation of lactic acid to pyruvic acid followed by decarboxylation and (ii) decarbonylation of lactic acid to acetaldehyde followed by oxidation. In the operating conditions we used, the catalyst is very active (total conversion of lactic acid) and selective towards acetic acid (100% selectivity). A 100% yield into acetic acid is hence obtained.

“…They described that the simultaneous presence of V and Mo enhances the redox properties of the catalysts and, thus, their reactivity. The improved catalytic properties of Mo-V-O oxides have also been reported for partial oxidation reactions, such as the dehydrogenation of propane [38][39][40], propane ammoxidation to acrylonitrile [41][42][43], or the selective propane oxidation into acrylic acid [44,45]. It has been demonstrated that molybdenum favors the presence of reduced vanadium V 4+ species, which are stabilized in a rutile-like structure that is responsible for the redox cycle [46].…”

V-containing mixed oxide catalytic materials are well known as active for partial oxidation reactions. Oxidation reactions are used in industrial chemistry and for the abatement of pollutants. An analysis of the literature in this field during the past few years shows a clear increase in the use of vanadium-based materials as catalysts for environmental applications. The present contribution makes a brief revision of the main applications of vanadium containing mixed oxides in environmental catalysis, analyzing the properties that present the catalysts with a better behavior that, in most cases, is related with the stabilization of reduced vanadium species (as V4+/V3+) during reaction.

“…They stated that vanadia-based catalyst is the most efficient for oxidative catalytic conversion of propane to propylene and oxygenates such as acrolein and acrylic acid. Meanwhile, Guerrero-Perez et al (2004) also showed the importance of vanadium in mixed Mo-V-Sb-Nb-O system for propane ammoxidation. In their research, it was shown that a bulk SbVO 4 oxide, containing traces of V 2 O 5 crystals is capable to produce higher yield of acrylonitrile as compared to the reported result previously (Guerrero-Perez et al 2004).…”

Naraschewski et al (2011a) studied the different vanadium, V content (0.07, 0.14, and 0.22) and the results showed that the activity of the catalysts increasing with the increasing of V content hence proved that V is the key element for propane oxidation.…”

The use of different vanadium sources in the synthesis of multi-metal MoVTeNb oxide catalysts has been investigated for their effect on the physicochemical properties of catalysts. Metal oxides were synthesized by slurry method assisted with a microwave irradiation. Vanadium pentoxide (V2O5), vanadyl sulphate (VOSO4) and ammonium metavanadate (NH4VO3) were used as the vanadium sources, respectively. X-ray diffraction (XRD) pattern showed the existence of orthorhombic (M1) phases in all catalysts. The catalyst prepared using V2O5 produced the highest formation of the phase. This was further supported by Inductive Couple Plasma-Atomic Emission Spectroscopy (ICP-AES), which showed that the V2O5 catalyst has the highest V: Mo ratio, mainly responsible for the high catalytic activity. Temperature Programmed Reduction in Hydrogen (H2-TPR) showed better reducibility for the catalyst when compared to the others. Temperature Programmed Reaction (TPRn) confirmed that the oxidants active for propane conversion into acrylic acid were originated from the lattice of the catalyst.
