TL;DR: Time-resolved in situ x-ray absorption spectroscopy shows that when either αI-VOPO4/SiO2 or (VO)2P2O7/ SiO2 catalysts are exposed to n-butane, the rate of maleic anhydride formation is proportional to the rate-determining step in the reaction sequence, and suggests that V5+ species may play a role in the initial hydrogen abstraction from n- butane.
