Abstract:Bismuth oxybromide (BiOBr) is a promising photocatalytic
semiconductor
material due to its unique hierarchical structure and band structure.
However, its photocatalytic applications are restricted due to its
narrow visible-light absorption range and poor photooxidation capability.
In this study, BiOBr1–x
I
x–y
with rich surface Br vacancies
(BrVs-rich BiOBr1–x

) was created via a facile
indirect substitution strategy. Benefiting from the broadened visible-light
response range and reduced recombination r… 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.
