A single‐compound source of B, C, and N was used for the growth of vertically aligned BCN (VA‐BCN) nanotubes (NTs). Owing to a synergetic effect of co‐doping of C nanotubes (CNTs) with N and B, the VA‐BCN NTs show significantly improved electrocatalytic activity (e.g., current density) for the oxygen reduction reaction compared to undoped VA‐CNTs, CNTs doped with only B or N (VA‐BCNT, VA‐NCNT), and a commercial Pt/C electrocatalyst (see picture).
