摘要: Nitrogen-doped carbon nanotubes (NCNTs) have been successfully synthesized via the direct solid pyrolysis of Zn–Fe-ZIF and N content, doped state, diameter formation temperature NCNTs can be finely tuned by mixing with proper amounts dicyandiamide (DCDA). DCDA serves as extra nitrogen supplier favors at relatively low due to its inducing effect for graphitic structure. The NCNTs, iron species high N, exhibit higher catalytic activity than commercial Pt/C oxygen reduction electrocatalysts in alkaline solution.
