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 (35.60%) 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 CO conversion.
采用反溶剂法在ReS纳米片上生长CsPbBr量子点以形成CsPbBr@ReS异质结。对样品的组成、形貌、空间分布和光吸收进行了表征。CsPbBr@ReS-15不仅由于光吸收和Z型电荷迁移的改善而表现出比CsPbBr更高的光催化性能，而且由于优异的光催化活性、增加的微放电时间和改善的放电均匀性，在介质阻挡放电（DBD）等离子体中还具有更高的CO转化率（35.60%）和能量效率（13.10%）。这项工作为等离子体光催化CO转化提供了一种策略。
