Enhanced CO conversion in dielectric barrier discharge plasma coupled with a heterojunction photocatalyst.

CsPbBr quantum dots were grown on ReS nanosheets to form CsPbBr@ReS heterojunctions using an anti-solvent method. The composition, morphology, spatial distribution, and optical absorption of samples were characterized. CsPbBr@ReS-15 exhibits not only a higher photocatalytic performance than CsPbBr due to the improved optical absorption and Z-scheme charge migration, but also a higher CO conversion ratio (35.
