ElsevierHernández Morejudo, S.; Masso Ramírez, A.; García-González, E.; Concepción Heydorn, P.; López Nieto, JM. (2015). 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.
