| Abstract: | As shown by temperature-programmed desorption (TPD), the quantity of reversibly chemisorbed propane on MoO3 passes through a maximum depending on the degree of surface reduction. Using the ESR method, it is shown that the centers of propene chemisorption do not contain Mo5+ ions but presumably isolated Mo4+ ions.
