摘要：

The electronic structure of the model alumina-chromium catalyst CrOx/Al2O3 for isobutane isomerization was investigated using the method of steady-state photoluminescence (PL). The chromium content varied in the investigated samples from 0.1 to 11.0 wt % in terms of Cr2O3. The luminescence and luminescence excitation spectra of Cr3+ were recorded under conditions of strong reabsorption. The feasibility of the Cr3+: Al2O3 (α-, γ-Al2O3) polymorphic phase detection and separation of the surface and bulk luminescence was shown. The Cr3+ luminescence and luminescence excitation spectra of the industrial catalyst IM-2201 were recorded. © 2014, Pleiades Publishing, Ltd.
