Noble metals change everything: The introduction of noble metals (M) into zeolites causes a decrease in the strength of Brønsted acid sites (Si(OH)Al). This effect is attributed to the charge transfer between the noble metal and the support-framework oxygen atoms, which affects the OH bond strength in the Si(OH)Al groups.
