A novel carbon‐nanotube–graphene hybrid nanostructure is developed using an aerosol‐assisted assembly approach. After doping with nitrogen and phosphorus, the prepared hybrid nanomaterials exhibit excellent electrocatalytic performance for oxygen reduction in both alkaline and acidic media. This research presents a continuous and low‐cost route to prepare high‐performance metal‐free electrocatalysts while replacing Pt‐based materials.
