摘要：
A photocatalyst comprising CdTe quantum dots and V-doped In2S3 exhibits a strong interfacial built-in electric field and an interfacial trapping state that provide sufficient driving force for extracting excitons and separating carriers during photocatalytic water splitting. Multiple excitons can be generated per photon and exploited to achieve an internal quantum efficiency of more than 100% for hydrogen production.
