Abstract

Low temperature oxygen chemisorption (LTOC) has been applied to characterize a series of TiO2 and ZrO2 supported Mo-oxide catalysts. The monolayer coverage of the surface is completed when the Mo loading reaches 6% and 4% on the TiO2 and ZrO2 supports, respectively. The results are explained with the help of a “Patch” model of the Mo-oxide phase.

Abstract

Низкотемпературная хемосорбция кислорода использовалась для характеристики серии Mo-окисных катализаторов на TiO2 и ZrO2 носителях. Монослойное покрытие поверхности завершается когда содержание Mo на TiO2 и ZrO2 носителях достигает 6% и 4%, соответственно. Результаты объясняют на основе модели “Patch” Mo-окисной фазы.
