Designing of one-dimensional C/Ce-compound composite materials.

Graphical abstract Highlights • One-dimensional C/Ce-compound (CeF 3 and CeO 2) composite materials were successfully designed. • CeF 3 and CeO 2 nanoparticles were uniformly dispersed in the porous nanofiber framework. • The porous nanofiber skeleton was beneficial to overcome the drawbacks of nanoparticles. Abstract For practical application of Ce material, one-dimensional C/Ce-compound (CeF 3 and CeO 2) composite materials were successfully designed. Carbon skeleton with unique interconnected porous structure and high specific surface area were manufactured by electro-blown spinning method, using polyvinyl pyrrolidone as the carbon precursor and polytetrafluoroethylene as the pore forming agent. CeF 3 and CeO 2 nanoparticles were uniformly doped in PCNF framework by in-situ encapsulation and hydrothermal methods, respectively. The porous nanofiber skeleton was beneficial to overcome the agglomeration and recycling problem of Ce-compound nanoparticles. This designed structure provided a promising strategy to ameliorate nanostructure material, suggesting potential application in catalyst and energy storage system. [ABSTRACT FROM AUTHOR]
