英文摘要two-dimensional materials based on ternary system of b, c and n are useful ranging from electric devices to catalysis. the bonding arrangement within these bcn nanosheets largely determines their electronic structure and thus chemical and (or) physical properties, yet it remains a challenge to manipulate their bond structures in a convenient and controlled manner. recently, we developed a synthetic protocol for the synthesis of crumpled bcn nanosheets with tunable b and n bond structure using urea, boric acid and polyethylene glycol (peg) as precursors. by carefully selecting the synthesis condition, we can tune the structure of bcn sheets from s-bcn with b and n bond together to h-bcn with b and n homogenously dispersed in bcn sheets. detailed experiments suggest that the final bond structure of b and n in graphene depends on the preferentially doped n structure in bcn nanosheets. when n substituted the in-plane carbon atom with all its electrons configured into the pi electron system of graphene, it facilitates the formation of h-bcn with b and n in separated state. on the contrary, when nitrogen substituted the edge-plane carbon with the nitrogen dopant surrounded with the lone electron pairs, it benefits for the formation of b-n structure. specially, the compound riched with h-bcn shows excellent orr performance in alkaline solution due to the synergistic effect between b and n, while s-bcn dominant bcn shows graphite-like activity for orr, suggesting the intrinsic properties differences of bcn nanosheets with different dopants bond arrangement.
