Abstract:
XRD analysis, electron paramagnetic resonance (EPR), and electron-nuclear double resonance (ENDR) in conjunction with molecular anthraquinone probe, were: used to study the properties of various alumnas. It was demonstrated that the use of the ENDR method for analyzing the hyperfine coupling of the unpaired electron with the aluminum and hydrogen nuclei of the paramagnetic species arising at the surface upon anthraquinone adsorption makes it possible to determine the structure of surface complexes even when EPR spectra are insufficiently resolved. It was established that various complexes are formed at the surface of the alumnas due to changes in the positions of acceptor surface sites participating in the reaction.
