Description:
Advancement of the synthetic performance of photocatalysts in environmental applications has been the most clinging pursue in relevant research fields. In this article, we propose a novel design strategy of an efficient visible-light photocatalyst with versatile advantages for environmental remediation. Flexible SiO 2 nanofibers were prepared with sol–gel and electrospinning techniques, followed by uniform anchoring of Bi 2 WO 6 nanoplatelets on the fibers’ surface, forming unique hierarchical SiO 2 –BiWO 6 composite fibers. Benefitting from the combination of the advantages from both the SiO 2 nanofibers and the Bi 2 WO 6 nanoplatelets, the film composed of SiO 2 –Bi 2 WO 6 fibers simultaneously possess high visible-light photocatalytic reactivity, good flexibility, and excellent thermal stability, affording many potential applications especially in environmental remediation. Water purification performance of the SiO 2 –Bi 2 WO 6 fibers film was evaluated here as an application example, and the results demonstrated are intriguing.
