Molybdena, both unsupported and supported on alumina (15 percent MoO/sub 3/), chemisorbs oxygen at --195/sup 0/C after pre-reduction in hydrogen. Unsupported, pre-reduced molybdena samples, having different total surface areas, give about the same ratio of total area to chemisorbed oxygen. This ratio has been applied to supported molybdena to deduce the equivalent molybdena surface area, which in several samples was about one-fourth of the total area.
