Abstract

Supported Ru/X catalysts (X: SiO2, Al2O3, SiO2·Al2O3, HY) have been investigated by IR and TPR (temperature programmed reduction). Due to interaction between Ru and Lewis or Brönsted sites of the support, the Ru sites become electron-deficient. Stronger acidity of the support makes the Ru sites more electron-deficient, and as a result, adspecies of Ru+δ (CO)4 or Ru+δ(CO)2 can occur more easily.

Abstract

Нанесенные катализаторы Ru/X (X:SiO2, Al2O3, SiO2·Al2O3, HY) исследованы с помощью ИК-спектроскопии и ТПВ. Вследствие взаимодействия Ru с льюисными и брёнстэдными центрами рутениевые центры приобретают электронную дефицитность. Повышенная кислотность носителя увеличивает электронную дефицитность рутениевых центров, в рузультате чего легче образуются аддитивы Ru+δ(CO)4 или Ru+δ(CO)2.
