Electrocatalysts for the oxygen reduction reaction (ORR) are essential in a variety of clean-energy devices, such as fuel cells and zinc–air batteries. Here we report poly(bis-2,6-diaminopyridinesulfoxide) as an active and stable ORR catalyst under alkaline conditions. It has no crossover effect of methanol, and CO toxicity is negligible, suggesting its potential as a cathode catalyst for alkaline fuel cells.
氧还原反应(ORR)的电催化剂在燃料电池和
锌-空气电池等各种清洁能源设备中至关重要。在此,我们报告了聚(双-2,6-二
氨基吡啶亚砜)作为碱性条件下活性稳定的 ORR 催化剂的情况。它没有
甲醇的交叉效应,
一氧化碳的毒性也可以忽略不计,这表明它具有作为碱性燃料电池阴极催化剂的潜力。
