Enhanced CO2 conversion in dielectric barrier discharge plasma coupled with a heterojunction photocatalyst

CsPbBr3 quantum dots were grown on ReS2 nanosheets to form CsPbBr3@ReS2 heterojunctions using an anti-solvent method. The composition, morphology, spatial distribution, and optical absorption of samples were characterized. CsPbBr3@ReS2-15 exhibits not only a higher photocatalytic performance than Cs...

Description
Summary:CsPbBr3 quantum dots were grown on ReS2 nanosheets to form CsPbBr3@ReS2 heterojunctions using an anti-solvent method. The composition, morphology, spatial distribution, and optical absorption of samples were characterized. CsPbBr3@ReS2-15 exhibits not only a higher photocatalytic performance than CsPbBr3 due to the improved optical absorption and Z-scheme charge migration, but also a higher CO2 conversion ratio (35.60%) and energy efficiency (13.10%) in the dielectric barrier discharge (DBD) plasma due to superior photocatalytic activity, increased micro-discharge time, and improved discharge uniformity. This work provides a strategy for plasma photocatalytic CO2 conversion.
