摘要：

3d transition metals or their derivatives encapsulated in nitrogen-doped nanocarbon show promising potential in non-precious metal oxygen electrocatalysts. Herein, we describe the simple construction of a bifunctional oxygen electrocatalyst with a "framework-active sites" structure, namely Fe/Fe3[email protected] ([email protected]) nanoparticles encapsulated in 3D N-doped graphene and bamboo-like CNTs ([email protected]/NCNTs). The [email protected] structure provides additional electrons on the carbon surface, promoting the oxygen reduction r...
