The Catalytic Activity of The Spinel Fe_xO Catalyst Synthesized With Magnetic Field

The catalytic activity of the spinel Fe_xO catalysts was evaluated by decomposition of H₂O₂. It was discovered that the ferrimagnetic Fe_xO （x=0.7-0.9） catalytic synthesed in magnetic field and the catalytic reaction in magnetic field could increase reaction rate and proved that this reaction is first order. When x=0.8-0.9 reaction Rate Constant has maximum. This paper present a magnetic criterion for catalytic reaction and indicates a direction for increasing catalytic reaction rate.
