Abstract

The interaction of NO and NO+CO mixtures with Fe2O3 has been studied by IR spectroscopy. The conclusion has been made that adsorption bands in the region of 1200–1700 cm−1 belong to nitrite-nitrate structures, the band at 1810 cm−1 characterizes catalytically active particles of NO adsorbed on reduced surface sites, Fe2+, the bands at 2210 and 2240 cm−1 are due to vibrations of gaseous N2O.

Abstract

Методом ИК-спектроскопии исследовано взаимодействие NO и смеси NO+CO с поверхностыо Fe2O3. Сделано заключение, что полосы поглощения в области 1200–1700 см−1 принадлежат нитрито-нитратным структурам; максимум 1810 см−1 характеризует каталитически активные частицы NO, адсорбированные на восстановленных центрах поверхности, Fe2+; максимумы 2210 и 2240 см−1 относятся к колебаниям газообразных молекул N2O.
