- Abstract
- In this work, we report on the preparation of the anodically-grown TiO2 nanotube arrays sensitized with In2S3 nanoparticles by using the SILAR (successive ionic layer adsorption and reaction) process. We evaluate the photo-catalytic properties of the prepared hetero-structures under visible-light illumination. The results reveal that the TiO2/In2S3 system has enhanced photo-catalytic characteristics including higher chopping height. Improved performance of the heterojunction is attributed to the narrower band gap of In2S3 and its favorable position within the conduction band relative to that of TiO2.
