Реферат:
Elucidation of the oxygen activation pathways are very important for the understanding the mechanism of oxidative action of monooxygenase type enzymes. The Cu-containing zeolites are of interest for the biomimetic approach due to the square-plain coordination of Cu(II) ions in copper oxide/hydroxide clusters and nanoparticles, easy transformation Cu(I) – Cu(II), and formation of alfa–like site. Here the DR UV-Vis spectroscopy was used to reveal condition where a peroxo/oxo complexes copper (II) are formed in CuZSM-5 catalysts. Cu-ZSM-5 possess the capability to stabilize copper(II) pero/oxocomplexes at treatment by hydrogen peroxide in alkaline solution as well as high-temperature calcination in O2-containing atmosphere. Peroxocomplexes copper(II) with terminal OOH-group are formed in H2O2 solution and characterized by CTB L-M 21500 and 35500 cm-1. They contain two copper ions located near and long distance, respectively. Oxocomplexes dicopper(II) with bridged ОО-group (CTB L-M 26500 –28000 cm-1) are formed at activation in H2O2 and in O2.
