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 … WebIn this work, we prepared silica-supported copper-bismuth oxide catalysts via incipient-wetness impregnation method. This Bi-doped catalyst exhibits an excellent performance in carbon monoxide oxidation with a reaction rate at 0.6 μmol CO ·g cat 1 ·s 1 at 170°C, which is about ten times of that for pure copper-silica catalyst.
