摘要: Abstract Mo-V-Te and Mo-V-Te-Nb mixed oxide catalysts, with different Mo/Te, Mo/V Mo/Nb atomic ratios have been prepared from aqueous solutions of the corresponding salts, dried at 120 °C heat-treated 600 °C for 2 h in a N2 stream. They characterised by several physico-chemical techniques (AAS, SBET, XRD, DRS-UV-Vis) tested selective oxidation both propane propene. Low specific surface areas obtained all cases. However, nature crystalline phases catalytic performance depend strongly on catalyst composition. All catalysts were active propene but only some Mo-V-Te-Nb-O also to acrylic acid. The is discussed.
