CdS nanoparticles sensitized high energy facets exposed SnO2 elongated octahedral nanoparticles film for photocatalytic application
Source abstract
Abstract
Abstract The fabrication of well-defined semiconductor based SnO2 heterostructure is still a great challenge. In this study, SnO2(TiO2) elongated octahedral nanoparticles film was directly produced on FTO substrate by hydrothermal approach and TiCl4 post-treatment. As a light absorber, CdS nanoparticles were assembled onto the TiCl4 -treated SnO2 elongated octahedral nanoparticles (SnO2(TiO2)). We investigated the photocatalytic and photoelectrochemical properties of the prepared SnO2(TiO2)/CdS films. The study found that the prepared SnO2(TiO2)/CdS(6) heterostructure showed much higher photocatalytic activities for the degradation of the methyl orange (MO) under visible light irradiation in comparison with individual SnO2(TiO2) film photocatalyst. The significantly enhanced photocatalytic performance of the SnO2(TiO2)/CdS(6) sample is due to the absorption of visible light and the formation of type-II heterostructure, which plays a role in the effective charge separation. Moreover, these SnO2(TiO2)/CdS films photocatalyst are directly produced on FTO substrates, making the photocatalyst collection and recycling easier than the powders photocatalyst.
