Abstract

TPR, XPS and PMR spectroscopic studies of the interaction of H2 with Rh/La2O3 and Pd/La2O3 catalysts have revealed that the reduction of oxidized metals on La2O3 takes place at T<400 K with the formation of hydrides and hydrogen transfer to the support. The latter is evidenced by the hydrogenation of CO3 2− groups present on La2O3.

Abstract

С использованием методов температурно-программируемого восстановления РФЭС и ЯМР1H спектроскопии исследовано взаимодействие H2 с катализаторами Rh/La2O3 и Pd/La2O3. Восстановление окисленньх металлов на La2O3 происходит при температуре выше 400 К. Было зарегистрировано образование гидридов и перенос водорода на носитель. Последнее проявилось в гидрировании CO3 2− групп, присутствующих на La2O3.
