Catalytic Activities of α, β, γ - Bismuth Molybdates for Selective Oxidation of Propylene to Arcrolein

Abstract

Since the order of activity of α, β, γ - bismuth molybdates has been debated in the literature, this article aims to clarify this by testing catalytic activity of three phases prepared by different methods, calcined at different temperatures. The impurity by other phases is one reason differentiate catalytic activity of these catalysts. It can be said that the order of three pure phases is: β slightly > α > γ.Keywords: bismuth molybdates, propylene, catalysts, selective oxidation
