MoVTeNbOx is, by far, the most selective catalyst towards acrylic acid and achieves a maximum of 71.3 % selectivity at 350 ºC at propane conversion of 26.1%. MoVOx, VPP and a-VPP reach significant, although lower, acrylic acid selectivities (7.2, 18.6, and 14.2 %, respectively). The maximum selectivity for MoVOx occurs at 225 ºC. For VPP and a-VPP the optimal temperatures with respect to selectivity are 400 and 350 ºC, respectively. This is in line with the fact that MoVOx is active at lower temperatures, while VPP and a-VPP require higher temperatures to convert propane (Fig. ). Finally, V2O5 achieves a much lower acrylic acid selectivity of 2.3%. The catalysts β-VOPO4, α-VWOPO4, α-VOPO4 and VWPOx are unselective towards acrylic acid under the reaction conditions considered. The presence of such diverse scenarios in the dataset is crucial for the success of the AI approach. activation energy of conductivity
