The development of low-cost non-noble electrocatalysts with high activity and durability is highly desirable for renewable and sustainable energy applications. Prussian blue (PB) analogues with the structure of transition metal–organic frameworks (MOFs) are viewed as attractive candidates for high-performance electrocatalysts, while how to achieve the decoration of metal sites without damage for improved reactivity is still challenging. Herein, a nanocomposite catalyst based on PB analogues on cobalt–nitrogen-doped porous hollow carbon microspheres (PB-Co/Co–N-PHCS) was synthesized by a facile hydrothermal method. Benefiting from multiple active sites, hierarchical porous structure, and high conductive hollow carbon shell, the catalyst showed outstanding electrocatalytic activity and durability for an oxygen evolution reaction (OER). More importantly, PB-Co/Co–N-PHCS also can serve as a bifunctional electrocatalyst for overall water splitting with high durability. This pioneering work provides a clue for the preparation of a new class of high-performance Prussian blue analogue-based hybrid electrocatalysts.

钴基普鲁士蓝类似物/双掺杂空心碳微球杂化体的合成作为高性能双功能电催化剂，用于析氧和总水分解
对于可再生和可持续能源应用，非常需要开发具有高活性和耐久性的低成本非贵金属电催化剂。具有过渡金属-有机骨架（MOF）结构的普鲁士蓝（PB）类似物被认为是高性能电催化剂的诱人候选物，而如何在不损坏金属部位的情况下进行修饰以提高反应性仍然是一个挑战。在本文中，通过便捷的水热法合成了基于PB类似物的钴-氮掺杂多孔空心碳微球（PB-Co / Co-N-PHCS）纳米复合催化剂。得益于多个活性位，分层的多孔结构和高导电性的中空碳壳，该催化剂显示出出色的电催化活性和氧释放反应（OER）的耐久性。更重要的是，PB-Co / Co-N-PHCS还可以用作双功能电催化剂，具有高耐久性，可用于整体水分解。这项开创性的工作为制备新型的高性能普鲁士蓝类似物基杂化电催化剂提供了线索。
