Abstract:Developing highly active catalysts, which possess highly dispersed small active particles, strong metal−support interaction (MSI) and abundant oxygen vacancies, has attracted much attention in the steam reforming of biomass tar. In this study, a series of Ce-promoted lignite-char-supported Co catalysts (Co−Ce/C) was prepared via ion exchange combined with an impregnation method. A smaller average metal particle size (4.22 nm), higher reduction degree (90%), larger number of oxygen vacancies (58%) and stronger … 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.
