plexes interfere with formation of cluster structures. The heat treatment of this sample causes the transference of isolated copper cations on SII and SI sites in synthetic X and Y zeolites. Cu2 + ions localized in sodalite cavities in SII raquo ;, under influence of molecules of alcohol at reaction temperatures migrate in large cavities - sites SIII and complete coordination up to octahedral at the expense of molecules of alcohol.
Conclusions
, the catalytic activity of the zeolites and HTSC-materials in the reaction of the oxidative dehydrogenation of C1-C2 alcohols is determined by presence of the identical active sites - the associates of copper ions with oxygen; for zeolites they are migrate in to the big cavities - copper ions with extra coordination by oxygen, and for superconductive cuprates they are the fixed - O - Cu - O - chains or CuO2 planes, which are capable to change their coordination at loss of oxygen.
