Could zeolites make cigarettes safer to smoke?


A self-protecting zeolite catalyst that degrades the carcinogens in cigarette smoke has been reported by scientists.

The zeolite – which is prepared in a one-step hydrothermal crystallisation without any post treatment or shape direction – selectively breaks down tobacco specific nitrosamines (TSNA) carcinogens in environmental cigarette smoke. The researchers have mixed the zeolite with tobacco inside cigarettes and report ‘high selectivity in the removal of TSNA’.
