Alumina-supported manganese oxide catalysts as well as the parent formates were characterized my means of FTIR spectroscopy and nitrogen physisorption. Two different manganese formate solutions are used for the impregnation of alumina (4.8 and 8.0 mass%). The infrared bands in the high frequency reg
## Fe-oxide/MgO (5-30 mol% Fe) was prepared by calcination of coprecipitated precursors. Reducibility in H, at 693 K was measured gravimetrically and volumetrically. All samples yielded metallic iron (Fe") suitable for catalytic use but much unreduced Fe\*+ remained, stabilized by the MgO. The mea
