Аннотация: Abstract: Vacuum-arc synthesis of nanopowders based on zirconia and metal-organic framework structures was carried out using low-pressure arc discharge plasma. The obtained material was studied using a number of techniques (XRD, IR, TEM, DTA). The TEM technique showed that Zr-MOF represents strongly agglomerated particles of nearlyПоказать полностьюspherical shape. The image clearly shows the crystal ordering of the nanoparticles with a large (up to 2 nm) lattice constant. The sizes of particles vary in the range from 5 to 30 nm. The mean particle size is 9.4 nm. XRD showed that the fraction of ZrO relative to Zr-MOF calculated according to the most intense lines of the X-ray diffraction pattern is 65%. Results of XRD agree well with IR studies. The DTA curve shows a continuous exothermic process, which is associated with a number of features of plasma chemical synthesis and morphology of the obtained nanoparticles, which is in full accordance with the study using transmission electron microscopy. © 2022, Pleiades Publishing, Ltd.
