Abstract:This article presents new results concerning a bistability phenomenon observed recently in the oxidative dehydrogenation of 2 -propanol over copper catalysts. In this system, an activity hysteresis loop is observed when the partial oxygen pressure is varied. This bistability has been explained by the oxidation of metallic copper when the partial oxygen pres sure increases and copper oxide reduction when the partial oxygen pressure decreases. In the experiments reported here, an external second phase O,, SnO,, … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
