CO2 chemisorption, BET surface area and the degree of reduction of Mo(VI) (e/Mo) have been determined in MoOx/Al2O3 samples, reduced with hydrogen at temperatures between 673 and 1173 K. The free alumina surface figures calculated from the surface area and e/Mo values were identical with those obtained from direct CO2 chemisorption measurements. This identity indicates that all of the oxygen ions of the surface molybdenum-oxygen species block the alumina surface.
