“…A number of assumptions on how the MoVTeNb catalyst works suggested [3][4][5] In the previous article, it has been described the reaction kinetics and mechanism of propane partial oxidation to acrylic acid on diluted MoVTeNbOx mixedoxide catalysts using high-throughput system (nanoflow reactor) [6]. This article more focus and deals with the similar reaction oxidation over diluted and leached MoVTeNbOx mixed-oxide catalysts.…”

“…Our experimental results lead to a similar conclusion that isobutene oxidation to MAL might occur over the M1 phase. Moreover, it has been reported that in the selective oxidation of propane over Mo-V-Sb-Nb-O catalyst, the presence of (M x Mo 1-x ) 5 O 14 (M = V or Nb) favors the formation of acrylic and acetic acid [45,46]. This proposal is also supported by our experimental results, however, as shown in Table 2, we found that the phase appears to be very low selective for the selective oxidation of isobutane to MAA.…”

A series of Mo-V-O catalysts were prepared by calcining the orthorhombic (M1) Mo-V-O phase containing precursors under different conditions (T = 500 or 600°C in atmosphere of N 2 or air) and tested for the oxidation of isobutane and isobutene. Characterization results (BET, XRD, XPS, FTIR, and TPR) showed that their structure and properties depend on the composition of the calcined samples and the calcined conditions. Catalytic tests showed that relatively high isobutane conversion and desired product selectivity can be achieved over MoV 0.3 -500-N and MoV 0.3 -600-A catalysts. It is also found that both orthorhombic M1 phase and (V 0.07 M 0.93 ) 5 O 14 phase are active and selective for the selective oxidation of isobutane to methacrolein, whereas higher selectivity toward methacrolein (40.4%) can be achieved over the former phase at a moderate isobutane conversion (6.4%). Moreover, (Mo 0.3 V 0.7 ) 2 O 5 phase may be propitious to complete oxidation for the selective oxidation of isobutane. On the other hand, the presence of V affects the activity and selectivity, and a low surface V 4? concentration prefers selective oxidation products. In addition, specific surface areas of the catalysts appear to be little important in determining the catalytic activation.

“…[1] They have received much attention due to their catalytic, [2] photochromic, and electrochromic properties. [3,4] MoO 3 -based catalysts are applied in the selective oxidation/ammoxidation of propene, [5,6] the partial oxidation of propane, [7] the selective oxidation of methane, [8,9] isomerization of olefins, [10] and in transesterification reactions. [11] In heterogeneous catalysis, the catalytic properties depend on the surface and bulk properties of the catalysts, such as the oxidation state of the ions, their local environment, and the type of exposed crystal planes.…”

composites are synthesized by CVD under atmospheric pressure using Mo(CO) 6 as the precursor and porous g-Al 2 O 3 particles in a horizontal, rotating, hot-wall reactor, which is also used for calcination in air. The composites are characterized by N 2 physisorption, atomic absorption spectroscopy, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmission electron microscopy (TEM), and laser Raman spectroscopy (LRS). The synthesized samples exhibit excellent porosity, even at high Mo loadings. A much higher Mo yield is achieved when applying sublimation-adsorption in static air instead of using flowing N 2 . A high degree of Mo dispersion on alumina is confirmed by XRD, LRS, and TEM; with a Mo surface density as high as 5.2 atoms nm À2, the sample is X-ray amorphous, there are no polymeric molybdate species detectable by LRS, and the island size of the molybdate species is about 1 nm according to TEM. The XPS analysis shows that exclusively Mo VI species are present on all synthesized samples. Thus, the applied rotating, hot-wall reactor achieves efficient mixing and homogeneous deposition.
