Journalism Department popup.description2 The correlation thermodynamically unstable structure of Fe80.0Si6.0B14.0, Fe78.5Ni1.0Mo0.5Si6.0B14.0, Fe81.0Ni1.0Mo0.5Nb0.5Si3.0B14.0, Fe73.1Nb3.0Cu1.0Si15.5B7.4, Fe66,5Ni17,0Cr8,0Mo0,1W1,9V0,4Si2,9B3,2 amorphous metallic alloys (АМA) with their catalytic activity in red-ox reactions has been studied. The phase and element composition of AMA has been studied by methods of X-ray diffraction, X-ray spectrum probe microanalysis and also by morphology of the surface of amorphous metallic catalysts. The АМA activity in reactions of NO, NO2 and H2O2 reduction was investigated by the voltametry method. The products of catalytic reactions were identified by the method of infrared spectroscopy. It is shown, that Fe66,5Ni17,0Cr8,0Mo0,1W1,9V0,4Si2,9B3,2 and Fe81.0Ni1.0Mo0.5Nb0.5Si3.0B14.0 amorphous metallic alloys (АМA) exhibit catalytic activity in reactions of nitrogen (II) oxide reduction to hydrazine and hydrogen peroxide decomposition accordingly. It is determined that the activation energy decreases for the2,5-3 times during catalytic Н2О2 decomposition in the AMA presence. The selective catalytic Fe-based systems doped with Ni, Mo and others alloying elements were produced by their magnetization in an alternating magnetic field with 50 Hz frequency. The remagnetization of AMA-catalyst in a alternating magnetic field leads to the renovation of its catalytic activity and the rate of Н2О2 catalytic decomposition increases for 2-2,5 times. Such effect is connected with the change of an element composition of the АМA surface layers. Product Description popup.authors popup.nrat_date 2020-04-02 Close
