Developing efficient catalysts for oxygen reduction reaction (ORR) remains an important task for future electrochemical energy applications. Here, we investigate the use of polymer brushes ionic liquid, poly(IL), as an emerging catalyst for ORR. Our results show that the poly(IL) presents a promising electrocatalytic activity which is correlated to the chemical composition and the nanostructuration of the polymer. Furthermore, we demonstrate the use of poly(IL) as a host guest platform for Pt catalyst, providing for the hybrid material a more efficient catalytic activity and tolerance to crossover reaction. In addition, we also reveal the potential use of poly(IL) and the hybrid material, poly(IL)/Pt, as an efficient bifunctional catalyst for ORR and the oxygen evolution reaction (OER).

聚合物刷离子液体作为氧还原和氧释放反应的催化剂

开发用于氧还原反应（ORR）的高效催化剂仍然是未来电化学能源应用的重要任务。在这里，我们研究聚合物刷离子液体，poly（IL），作为新兴的ORR催化剂的使用。我们的结果表明，聚（IL）具有良好的电催化活性，这与聚合物的化学组成和纳米结构有关。此外，我们演示了使用聚（IL）作为Pt催化剂的宿主客体平台，为杂化材料提供了更有效的催化活性和对交叉反应的耐受性。此外，我们还揭示了聚（IL）和杂化材料聚（IL）/ Pt作为ORR和氧释放反应（OER）的有效双功能催化剂的潜在用途。
