Abstract

129Xe nuclear magnetic resonance spectra of xenon adsorbed on supported platinum-alumina catalysts have been examined. The state of metallic platinum particles (Pto) was shown to be different for Pt/Al2O3 and Pt/Al2O3(Cl) samples. Some assumptions about the mutual arrangement of supported metallic particles have been made.

Abstract

Исследованы спектры ЯМР129Xe ксенона, адсорбированного на алюмоплатиновых катализаторах риформинга, содержащих платину в форме Pt0 и Pt(II). Показано, что состояние металлической платины (Pt0) отличается от образцов катализаторов, содержащих и не содержащих хлоридные добавки. Сделано заключение о характере взаимного расположения частиц Pt0 и Pt(II).
