論文簡介
Ammonium salts,(NH_4)_6HPMo_(11) MO_(40) (M=Ni,Co,Fe),have been investigated for the oxidation of propane,with molecular oxygen,at temperature ranging between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9 ℃/min. They were characterized by BET method,XRD,~(31)p NMR,UV-Vis and IR techniques. The catalysts were found active in the propane oxidation and selective to propene or acrolein,in particular for samples pre-treated with the heating rate of 9 ℃/min.
