摘要：

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).
