Iron molybdate catalyst suppliers
WebXPS studies of bulk iron molybdate have revealed that annealing at 400 °C facilitates the migration of molybdenum to the catalyst surface [ 21 ], even when present at low bulk levels. The majority of surface investigations however have exploited electron microscopy studies. WebNov 14, 2024 · A maximum 93% Mo was extracted from roasted catalyst in 5 M ammonia at 80°C for 5 h leaching condition. Then from the leach liquor, iron molybdate Fe 2 (MoO 4 ) 3 was synthesized by hydrothermal method in different iron precursors such as ferrous ammonium sulphate, ferric nitrate, and ferric sulphate.
