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/SnO2 nanofibers with controllable heterojunctions. Specifically, both of the TiO2 and SnO2 components 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.
在本通讯中，我们证明了采用并列双喷丝头的静电纺丝工艺是制备具有可控异质结的双组分TiO₂/SnO₂纳米纤维的一种简单方法。具体而言，纳米纤维中的TiO₂和SnO₂组分均完全暴露于表面。这种形态在光催化过程中充分利用了光生空穴和电子，从而导致高光催化活性。我们相信，这种通用方法可扩展用于制备其他新型高效双组分光催化剂。
