Abstract:Photocatalysis is extensively implemented in organic pollutant degradation, and the critical point is to develop outstanding and stable photocatalysts. Herein, the synthesis of coral reef-like α-Bi 2 O 3 /BiOBr heterostructure photocatalysts involves the in situ growth of BiOBr nanosheets onto α-Bi 2 O 3 , with the latter derived through calcination utilizing a bismuthbased metal−organic framework (CAU-17) as the precursor. Under simulated sunlight, the 20% α-Bi 2 O 3 /BiOBr heterojunction degraded nearly 97.7… Show more
Insights into the synthesis and structure of an n–n type BiOBr/TiO2 heterostructure with an S-scheme charge-carrier mechanism and its effect on photocatalytic dye degradation are presented.
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.
