Enhancement of acrylic acid yields in propane and propylene oxidation by selective P doping of MoV(Nb)TeO-based M1 and M2 catalysts

Research output: Contribution to journalArticle

Abstract

Selective doping of (M1) Mo7.8V1.2NbTe0.94O28.9 and (M2) Mo4.67V1.33Te1.82O19.82 phases with P significantly enhance acrylic acid yields (2-15%) in propane/propylene oxidation. Amorphous overlayers (Te-molybdate) seriously inhibit acrylic acid formation. Detailed mechanisms are presented.
