چکیده انگلیسی
Kinetics and mechanism of the hydrogen reduction of MoO3 to MoO2 were studied in this work. The experimental findings confirmed that the reduction of MoO3 to MoO2 was a consecutive reaction with the intermediate product Mo4O11. The dual reactions (MoO3 â Mo4O11, Mo4O11 â MoO2) occurred simultaneously, and the rate of the first reaction was higher than that of the second one. The reduction kinetics of MoO3 was analyzed according to a two-interface model, the predicted curves of which agreed well with the experimental results. Using this model, the rate controlling steps and the corresponding activation energies were obtained.
