Carbon‐Coated CdS Petalous Nanostructures with Enhanced Photostability and Photocatalytic Activity

With a bandgap ofaround 2.4 eV, which matches well with the visible spectralrange of solar irradiation, CdS exhibits excellent photocata-lytic activity because of its highly effective absorption of solarenergy. As a visible-light-driven photocatalyst, it has beenextensively investigated and its photocatalytic activity hasbeen found to be influenced by a variety of factors includingpreparation conditions, particle size, morphology, and crys-tallinity.
