Figure S 2: Methacrolein (MAL), COx and isobutene selectivity vs. isobutane conversion in the partial oxidation of isobutane. Mo8V2Sb90Ox catalysts were synthesized with slurry type method (a,▪▪▪) and with MHD pretreatment, by recirculation of the precursors for 30 min at 5 L/min in presence of magnetic field (0.33 T) (b,▬). Two samples were analyzed for each catalyst at each temperature: (1) 350 °C, (2) 375 °C, (3) 400 °C, (4) 425 °C, (5) 450 °C.

Figure S 3: Methacrolein (MAL) selectivity vs. isobutane conversion in the partial oxidation of isobutane. Mo8V2Sb90Ox catalyst was synthesized using magnetic field. Three consecutive runs were performed (a, b and c). Two samples were analyzed for each catalyst at each temperature: (1) 350 °C, (2) 375 °C, (3) 400 °C, (4) 425 °C, (5) 450 °C.
