Abstract
High photostable CdS nanoparticles modified with alkyl group were prepared by an improved microemulsion technique using hexanethiol (RSH) as co-surfactant. The surface-modified CdS nanoparticles (R-CdS) catalyzed the photooxidation of 4-chlorophenol via continuous bubbling oxygen under UV light. The photocatalytic oxidation activity of R-CdS nanoparticles was enhanced due to the high photostability generated by heat-treatment.
