Both the partially reduced and non‐reduced multi‐component heteropoly compound catalysts with Keggin structure were prepared and used for the selective oxidation of propane. The catalysts were characterized by IR, H 2 ‐TPR, NH 3 ,‐TPD, SEM and XRD. The addition of Cs increased the selectivity of acrylic acid and acetic acid. The selective oxidation performance was greatly improved with the addition of As. Among all of the tested catalysts, the catalytic performance of the Cs 1.8 Fe 0.16 H x PVAs 0.4 Mo 11 O 40 (non‐reduced) was the best and the maximum yield of acrylic acid reached 16.42%.
