“…There will be an increased demand for AA with the increasing concern for environment protection [5,6]. At present, the commercial production of AA through gas-phase catalytic oxidation of propylene and/or acrolein is a mature, widely practiced and competitive industrial process in the world [7,8]. To reduce the cost of production, many manufactures have improved or are improving this production technique for AA with respect to the improvement of catalytic performance and optimization of purification technology [9][10][11].…”

Preparation, characterization and catalytic behavior for propanepartial oxidation of Ga-promoted MoVTeO catalysts. Applied Catalysis A: General. 504:51-61. doi:10.1016/j.apcata.2014.12.039. The results showed that the addition of small amount of gallium significantly increase the selectivity to acrylic acid (AA) at low propane conversion. However, at high propane conversion, the selectivity to AA strongly depends on both the catalyst composition and the gallium incorporation method. The higher selectivity to acrylic acid over Ga-containing MoVTeO catalysts has been related to: i) structural changes in the M1 phase by the incorporation of Ga 3+ into the octahedral structural framework, and/or ii) incorporation of Ga 3+ species on the catalyst surface thus modifying catalysts acid properties.

“…The catalysts were prepared using a hydrothermal method and were calcined at 873 K in nitrogen for 2 hours to achieve the desired phase. Other researchers have embarked on studies of MoVNbOx catalysts with a tetragonal rutile structure, which exhibit very good activity as well 4,5,6,7,8,9 . Tellurium is no longer used as catalyst is due to its tendency to sublime during calcination.…”

Ni-, Co-, and Pt-promoted MoVNbOx mixed metal oxide catalysts were prepared by impregnation method. The physicochemical properties of the catalysts showed that the BET surface area of the promoted catalysts was lower when compared to the unpromoted catalysts due to the filling of open pores by the promoters. X-ray diffraction (XRD) analysis indicated that the main reflections were consistent with the tetragonal rutile structure. Three crystalline phases of (V 0.07 Mo 0.93 ) 5 O 14 , (Nb 0.09 Mo 0.91 )O 2.80 , and Mo 4 O 11 could also be observed. Induced Coupled PlasmaOptical Emission Spectroscopy (ICP-OES) displayed the loss of metal promoters, mainly due to sublimation during calcination with Pt-MoVNbOx. Temperature Programmed Reduction (H 2 -TPR) exhibited high reducibility for samples loaded with 10 -3 wt% promoter. The level of reduction declines with increased loads, suggesting a stronger oxygen bond in the promoted metal oxide catalysts.
