Heterojunctions of p-BiOI Nanosheets/n-TiO? Nanofibers: Preparation and Enhanced Visible-Light Photocatalytic Activity.


ABSTRACT: p-BiOI nanosheets/n-TiO? nanofibers (p-BiOI/n-TiO? NFs) have been facilely prepared via the electrospinning technique combining successive ionic layer adsorption and reaction (SILAR). Dense BiOI nanosheets with good crystalline and width about 500 nm were uniformly assembled on TiO? nanofibers at room temperature. The amount of the heterojunctions and the specific surface area were well controlled by adjusting the SILAR cycles. Due to the synergistic effect of p-n heterojunctions and high specific surface area, the obtained p-BiOI/n-TiO? NFs exhibited enhanced visible-light photocatalytic activity. Moreover, the p-BiOI/n-TiO? NFs heterojunctions could be easily recycled without decreasing the photocatalytic activity owing to their one-dimensional nanofibrous structure. Based on the above, the heterojunctions of p-BiOI/n-TiO? NFs may be promising visible-light-driven photocatalysts for converting solar energy to chemical energy in environment remediation.
