A novel (CdS-Mn/MoS/CdTe)-sensitized TiO nanotube arrays (NTAs) photoelectrode has been prepared by electrodeposite, successive ionic layer adsorption and reaction (SILAR) coupled with hydrothermal method. When a ZnS layer was added on the top of CdS-Mn/MoS/CdTe/TiO, a notable red-shift and high absorption was observed in the visible light region. The photocurrent density (mA/cm) systematically increases from TiO NTAs (0.43), CdTe/TiO (1.09), MoS/CdTe/TiO (1.80), CdS-Mn/MoS/CdTe/TiO (2.40), to ZnS/CdS-Mn/MoS/CdTe/TiO (3.41) under visible light irradiation, due to the type-II semiconductor heterostructures comprising multiple components with a staggered band offset. Such a heterostructure possesses an enhanced photocatalytic performance towards degradation of organic contaminant, e.g. P-Nitrophenol (PNP) and Rhodamine B (RhB).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
