Abstract

Based on the analysis of survey XPS spectra of 3%Ru/Al2O3 and 3%Ru/SPS catalyst samples before and after the catalytic test, the qualitative and quantitative elemental composition of the surface of these samples was established. Conditions for the 3% Ru/Al2O3 catalyst before the catalytic test of hydrated ruthenium (IV) was 23% and ruthenium (IV) oxide — 45%, respectively, and after — hydrated ruthenium (IV) was 21% and ruthenium (IV) oxide — 37%, respectively. Conditions for the catalyst 3% Ru/SPS before the catalytic test hydrated ruthenium (IV) was 29% and ruthenium (IV) oxide — 3%, respectively, and after — hydrated ruthenium (IV) was 22% and ruthenium (IV) oxide — 2 %, respectively.
