文摘
- •
Novel semiconductors decorated by CdTe QDs and/or Pt NPs were synthesized.
- •
Photodeposition and radiolysis is an effective method to obtaining Pt NPs.
- •
CdTe decorated samples were prepared by absorption of QDs on matrix surface.
- •
KTaO3/CdTe-Pt(R) showed highest photocatalytic performance.
- •
The enhanced performance was associated with electron trap mechanism.
