This information is relevant for the development of modern astrophysics, cosmology, reactor construction. The new experimental cross-sectional results will be used not only as input to astrophysical modeling of stellar nucleosynthesis, but also as new information for testing modern computer codes in statistical theory. In addition, the aim of this work will be to study the effect of gamma activation on the properties of nanoparticles of zirconium dioxide with their subsequent use for the sorption of actinides and catalysts in the conversion of hydrocarbons. popup.description2 The influence of -activation on the functional characteristics of ZrO2 nanoparticles in the process of heterogeneous catalysis of hydrocarbons on the methanol model at room temperature was investigated. Activation of ZrO2 nanoparticle samples was carried out by bremsstrahlung at the electron accelerator of the National Research Center of the Institute of Physics and Technology of the Russian Academy of Sciences with an electron energy of 22 MeV and a current of 500 μA. No other impurities were detected in the γ-spectrum of ZrO2 measured by a Ge(Li) detector. According to IR spectroscopy and X-ray diffraction, a high level of crystallinity and monophasicity was preserved in gamma-activated ZrO2 nanoparticles. The catalytic activity of unactivated and bremsstrahlung-activated zirconium dioxide nanoparticles on the nature of the methanol conversion model was compared using a powerful electron accelerator. It was shown that when activated ZrO2 nanoparticles are used as a catalyst, the yield of hydrocarbon products in methanol conversion increases by an order of magnitude relative to the same products in the case of unactivated ZrO2 nanoparticles. The mechanism of such methanol conversion may be associated with the synergism of large ionization losses of Auger electrons and the influence of highly reactive products that participate in heterogeneous catalysis.
