Improving the photoelectrochemical and photocatalytic performance of CdO nanorods with CdS decoration

Herein, we report an effective and simple strategy to greatly improve the photoactivity of CdO nanorods (NRs) by decorating them with CdS. The CdO–CdS heterostructured NRs grown on a FTO substrate exhibited substantially higher visible-light-driven photoactivity for a PEC cell and the degradation of methylene blue (MB) solution compared to CdO NRs.
