The design and synthesis of a multi-functional electrocatalyst with low cost and high efficiency is still a great challenge. Herein, we report the rational design and realization of a tri-functional electrocatalyst featuring Co/CoP embedded in a hairy nitrogen-doped carbon polyhedral (Co/CoP–HNC) derived from common metal organic frameworks (MOFs). The components of Co, CoP, and hairy nitrogen-doped carbon in the catalyst respectively render catalytic activity, high electrochemical surface area, and electronic conductivity. The synergy of the tailored Co/CoP–HNC catalyst provides high activity for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER). The catalytic performance and assembly feasibility are further demonstrated in overall water splitting and Zn–air battery tests, and both revealed high efficiency and long durability of the proposed electrocatalyst.

Co / CoP嵌入毛状氮掺杂的碳多面体中，作为先进的三功能电催化剂†

低成本和高效率的多功能电催化剂的设计和合成仍然是巨大的挑战。在本文中，我们报告了一种以Co / CoP为特征的三功能电催化剂的合理设计和实现，该Co / CoP嵌入从常见金属有机骨架（MOF）衍生出的毛状掺氮碳多面体（Co / CoP–HNC）中。催化剂中的Co，CoP和富氮的碳分别具有催化活性，高电化学表面积和电子传导性。量身定制的Co / CoP-HNC催化剂的协同作用可为氧还原反应（ORR），氧释放反应（OER）和氢释放反应（HER）提供高活性。催化性能和组装可行性在整体水分解和锌空气电池测试中得到了进一步证明，
