Pronounced catalytic activity of Fe0.08Cs2.5H1.26PVMo11O40 for direct oxidation of propane into acrylic acid

Abstract Fe 3+ or Ni 2+ -substitution for H + and V 5+ -substitution for Mo 6+ in Cs 2.5 H 0.5 PMo 12 O 40 greatly enhanced the catalytic activity for direct oxidation of propane into acrylic acid. Of the catalysts tested Cs 2.5 Fe 0.08 H 1.26 PVMo 11 O 40 gave the highest yield of acrylic acid, 13%.
