高温石墨化处理的碳纳米纤维表面重构形成多壁纳米回路，这些回路状结构可以使得Pt纳米颗粒在石墨化的纳米纤维上较为均匀的分散，同时由于石墨化的纳米纤维具有优异的导电性和抗腐蚀能力，显著提高了燃料电池阴极催化剂的性能及其寿命。

Abstract
Graphite nanofibers (GNFs), on which surface graphite edges were reconstructed into nano-loops, were explored as a cathode catalyst support for fuel cells. The high degree of graphitization, as well as the surface-reconstructed nano-loops that possess topological defects for uniform metal deposition, resulted in an improved performance of the GNF-supported Pt catalyst.
