摘要：Rocking-chair Capacitive Deionization (RCDI) is one of the most promising cell architectures for highly efficient capacitive deionization (CDI) to address the fresh-water shortage, and developing Cl--removal electrode materials of RCDI toward highly-efficient desalination (with high capacity and rate) is of utmost urgency. Herein we report our design on high-performance Cl--removal electrode material via controllable anchoring of bismuth oxychloride nanostructures (BiOCl; such as nanoplates, nanoflowers, and nanospheres) on electrospun carbon nanofibers (BiOCl-CNF) for RCDI. The BiOCl-CNF based RCDI system displays excellent Cl- storage capacitance as well as freestanding characteristics, which enables it to be a perfect electrode candidate for RCDI. By properly tailoring the composition of the hybrid material, the BiOCl-CNF based RCDI displays outstanding desalination efficacy in terms of desalination capacity (124 mg.g(-1)), energy consumption (66.8 Wh.m(-3)), and desalination rate (0.52 mg.g(-1).s(-1)), which are far more superior than the existing systems from the literatures, exemplifying the critical importance of delicate design in the Cl--removal electrode materials for improving the desalination performance.
