Active component management and microengineering of metal nanoparticles are significant challenges for efficient M/N/C electrocatalysts, as a crucial electrode material for reversible zinc-air batteries, because of the lack of a multifunctional structural strategy in the electrocatalytic preparation process. Here, a convenient, one-step pyrolysis method was introduced into the preparation process of a difunctional electrocatalyst, an Fe-, Co-, and N-codoped carbon-based cube hybrid (Co7Fe3/CFNC) with abundant active components, including metall...
