Preparation of iron molybdenum oxide promoted chromium oxide (Cr2O3/Fe2 (MoO4) 3) hasbeen done. The sample is synthesized by precipitation method. The performance of the catalyst is
evaluated by the catalytic oxidation of methanol to formaldehyde. For comparison, in this experiment
also use Fe2(MoO4)3 without promoter and Fe2 (MoO4)3 commercial. The samples are characterized by xray diffractometer (XRD) to determine its composition. XRD results indicate that the catalyst component
comprised of Fe2 (MoO4)3, Fe2O3, and MoO3. The reaction is conducted in a tubular reactor with fixed-bed
catalyst, operating at temperatures of 250, 300, 350 °C, and atmospheric pressure. The products are
analyzed by Shimadzu gas chromatography using a porapak-Q column. The highest yield of
formaldehyde of each catalyst, i.e: Fe2(MoO4)3, Cr2O3/Fe2 (MoO4)3 of 83%, 86% at temperatures of 300 °C
and Fe2(MoO4)3 commercial reach 96% at a temperature of 350 oC, respectively. The addition of Cr2O3 as
a promoter shows increased the activity of iron molybdenum oxide catalysts.
