Abstract

Adsorption of neopentane on faujasite, mordenite and ZSM-5 zeolites has been investigated by UV-VIS spectroscopy. At room temperature, UV-VIS active surface species were detected and assigned to alkenyl-type carbenium ions. Their formation was shown to be influenced by the overall acidity, the ratio of Brønsted to Lewis acidity and the zeolite structure.
