An Efficient Bicomponent TiO2/SnO2Nanofiber Photocatalyst Fabricated by Electrospinning with a Side-by-Side Dual Spinneret Method.

In this communication, we demonstrate that the electrospinning process with a side-by-side dual spinneret can be a simple approach for fabricating bicomponent TiO2/SnO2nanofibers with controllable heterojunctions. Specifically, both of the TiO2and SnO2components in the nanofibers are fully exposed to the surface. This morphology fully utilized the photogenerated holes and electrons during the photocatalytic process, thus leading to a high photocatalytic activity. We believe that this versatile approach can be extended to fabricate other novel high-efficiency bicomponent photocatalysts. [ABSTRACT FROM AUTHOR]
