A visible-light-responsive TaON/CdS photocatalytic film with a ZnS passivation layer for highly extraordinary NO₂ photodegradation.

ABSTRACT: Recently, TaON has become a promising photoelectrode material in the photocatalytic field owing to its suitable band gap and superior charge carrier transfer ability. In this work, we prepared a TaON/CdS photocatalytic film using a CdS nanoparticle-modified TaON film by the successive ionic layer adsorption and reaction (SILAR) method. For the first time, the ZnS nanoparticles were deposited on the TaON/CdS film using the same method. We found that pure TaON had a nanoporous morphology, thus resulting in high specific surface area and better gas adsorption capacity. Furthermore, the TaON/CdS/ZnS film displayed a highly efficient NO₂ photodegradation rate under visible light irradiation owing to its stronger visible light response, photocorrosion preventive capacity, and the high
