DESCRIPTION:Speakers: Kristina Shefer (Boreskov Institute of Catalysis SB 
 RAS)\nAlumina containing systems are of great significance for catalysis d
 ue to the unique properties of this oxide. These systems usually exist in 
 nanoscale state. Their composition and physicochemical properties depend o
 n the preparation conditions. The appearance of novel methods of alumina s
 ynthesis give a new stimulus to the study of their structure and propertie
 s. Therefore such substances are interesting objects for research.\nThe mo
 st reliable structural information is extracted from direct structural dif
 fraction methods. In the case nanoscale catalytic systems\, using special 
 methods which take into account the specific features of X-ray scattering 
 from small objects is required. In this work\, structural features of alum
 inа-containing systems are examined using PDF method. Applying this metho
 d needs obtaining diffraction data in a wide range of angles and with high
  intensity. X-ray diffraction patterns for constructing the experimental c
 urves were obtained on a high-resolution diffractometer at the Siberian Sy
 nchrotron and Terahertz Radiation Center (Institute of Nuclear Physics\, S
 B RAS? Novosibirsk). The considered aluminum oxides were obtained by diffe
 rent methods with varying synthesis parameters: deposition method\, alumin
 ate method\, sol-gel method\, CTA method. \nThe work was supported by Russ
 ian Foundation for Basic Research (project #19-03-00595) and by Ministry o
 f Science and Higher Education of the Russian Federation (project # ААА
 А-А17-117041710079-8).\n\nhttps://indico.inp.nsk.su/event/24/contributio
