Iron molybdate catalyst
WebBismuth molybdate catalysts have been used for partial oxidation and ammoxidation of light hydrocarbons since the 1950s. In particular, there is the synergy effect (the enhancement of the catalytic activity in the catalysts mixed from different components) in different phases of bismuth molybdate catalysts which has been observed and studied since the 1980s; … WebMay 23, 2015 · A mixed phase catalyst of iron molybdate with an excess of molybdena (25.9 % by weight) was prepared by acidification of a solution of ammonium heptamolybdate (BDH C99 %) to pH 2 using nitric acid (Fisher, Laboratory Grade), before drop-wise addition of iron nitrate (BDH, C98 %) with stirring at 60 °C.
