It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. Dibismuth trioxide is … WebWith these two-component catalysts, the first step, breaking the C-H bond, is catalysed by the more basic oxide, e.g. bismuth oxide. Molybdenum is involved in the next step - activation of a second hydrogen and insertion of an oxygen atom into the organic molecule. In this step molybdenum is reduced. ray wiltsey school loop
