Kinetics of oxidehydrogenation of propane over alumina-supported Sr-V-Mo catalysts

► Addition of Sr to V-Mo/Al2O3 catalyst improves its performance. ► Mars-Van Krevelen mechanism fits reactions catalyzed by V-Mo/Al2O3 ► Strontium doped V-Mo catalysts are best fitted with Langmuir-Hinshelwood mechanism.
