The presence of Cu on Rh/SiO2 inhibited H2 chemisorption at 303 K and suppressed CO hydrogenation. TPD study shows that chemisorption of H2 on Cu−Rh/SiO2 is an activated process at 303 K.

Присутствие Cu на Rh/SiO2 ингибирует хемосорбцию H2 при 303 К и подавляет гидрирование CO. Результаты исследований ТПД свидетельствуют о том, что хемосорбция H2 на Cu−Rh/SiO2 является активированным процессом при температуре 303 К.
