Abstract

ESR studies show taht the low temperature photoreduction of anatase in CO proceeds in both the fundamental and impurity light absorption regions of the oxide, leading to anion vacancies. Further irradiation in the presence of O2 leads to\(\boxed{O_3^ - }\) complexes, assigned to anion vacancies.

Abstract

Методом ЭПР показано, что низкотемпературное фотовосстановление анатаза в CO имеет место как в области собственного, так и примесного поглощения окисла и сопровождается образованием анионных вакансий. Последующее облучение в присутствии O2 приводит к образованию кислородных комплексов O 3 , связанных с наличием анионных вакансий.
