Flexible nanofiber assembled zinc–air battery: carbonization–phosphidation of metal–organic framework (MOF)/polyacrylonitrile nanofibers gives rise to a pearl necklace fibrous carbon catalyst with Fe‐N/Fe‐P dual active sites (Fe‐P/NHCF). This strategy puts forward a protocol to develop tailored geometries with dual active sites for the oxygen reduction reaction in alkaline/acid media, which is expected to promote devices of practical significance.

珍珠项链纤维状碳共享Fe–N / Fe–P双重活性位点，作为宽介质和液态/固态可充电锌空气电池中的高效氧还原催化剂

柔性纳米纤维组装锌-空气电池：金属-有机骨架（MOF）/聚丙烯腈纳米纤维的碳化-磷酸化产生了具有Fe-N / Fe-P双活性位（Fe-P / NHCF）的珍珠项链纤维碳催化剂。该策略提出了开发具有双活性位点的定制几何结构的方案，用于在碱性/酸性介质中进行氧还原反应，这有望促进具有实际意义的装置。更多细节可以在刘睿和吴梦辰的文章1901263中找到。
