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.

为了探究形态对石墨相氮化碳（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。在这两种形态中，管状GCN在ORR中与溶解氧发生反应，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，这突出了其在燃料电池中的适用性。
