Abstract

Adsorption of CO enriched with13C isotope was investigated on a CoO−MgO catalyst containing 3 at.% Co. It is argued that the ESR signal with g1,2=2.0054±0.0005; g3=2.0020±0.0005; A1=33 0e*; A2=11 0e; A3=63 0e, appearing in the course of adsorption may not be ascribed to CO −2 or CO −3 anion radicals but should be attributed to surface X−CO complexes of a carbonyl-like structure.

Abstract

Адсорбция CO, обогащенного изотопом C13, была исследована на катализаторе CoO−MgO, содержащем 3 ат.%-a Co. Дискутируэтся вопрос о том, что сигнал с g 11,2 =2,0054±0,0005, g3=2,0020±0,0005, A1=33 эрс, A2=11 эрс и A3=63 эрс, появляющийся в ходе адсорбции, вероятно следует приписывать не анион-радикалам CO −2 или CO −3 , а поверхностным комплексам X−CO со структурой, подбной карбониьной.
