为了探讨形态对石墨氮化碳（GCN）催化性能的影响，我们研究了两种不同形态的GCN在碱性介质中的氧还原反应（ORR）性能。其中，管状 GCN 与 ORR 中的溶解氧发生反应，其起始电位接近商业 Pt/C。此外，与 Pt/C 相比，管状 GCN 具有更高的稳定性和优异的甲醇耐受性，这强调了其对燃料电池的适用性。
To explore the effect of morphology on catalytic properties of graphitic carbon nitride (GCN), we have studied oxygen reduction reaction (ORR) performance of two different morphologies of GCN in alkaline media. Among both, tubular GCN react with dissolved oxygen in the ORR with an onset potential close to commercial Pt/C. Furthermore, the higher stability and excellent methanol tolerance of tubular GCN compared to Pt/C emphasizes its suitability for fuel cells.
