In this letter, we report a new method to fabricate side-by-side ZrO2 /PbO2 nanofibers using the DOSE (dual-opposite-spinneret electrospinning). Electrospinning, regarded as a simple, low-cost, and universal technique for fabricating submicrofibers and nanofibers, has been receiving more and more attention over the last 15 years. In addition to general beaded and nonbeaded thin nanofibers, other types of nanofibers with interesting morphology, such as core-shell nanofibers, hollow nanofibers, and side-by-side nanofibers, have been produced by electrospinning. A side-by-side structure allows both parts of the nanofibers to be exposed to the surface. Bicomponent side-by-side ZrO2 /PbO2 nanofiber photocatalysts have been fabricated via side-by-side electrospinning. Their study demonstrated that the photocatalytic degradation rate of Rhodamine B (RhB) dye on the side-by-side ZrO2 /PbO2 nanofibers was more than double that on the pure ZrO2 nanofibers.
