氧气还原反应（ORR）是多种燃料电池的阴极反应，但是动力学过程缓慢等问题制约了ORR性能的提高。制备以改性碳纳米管为载体的电催化剂是提高ORR性能的有效手段，受到越来越多研究人员的关注。介绍了国内外学者有关非共价改性碳纳米管用于ORR的最新研究进展，着重综述了小分子改性和聚合物改性的方法，主要包括电中性小分子、离子型电解质、电中性高聚物、离子型聚电解质改性，并对非共价改性碳纳米管基ORR催化剂的研究前景进行了展望。

oxygen reduction reaction (ORR) is a cathode reaction for many kinds of fuel cells, but its slow dynamic process restricts the improvement in its performance.More and more researchers focus on the preparation of electrocatalysts with modified carbon nanotubes (CNTs) as carrier to enhance the performance of ORR.This paper introduces latest research progress on noncovalently-modified CNTs for ORR and emphatically summarizes the modification methods using small molecule substances and polymers, including electrically neutral small molecules, ionic electrolytes, electrically neutral polymers and ionic polyelectrolytes.Finally, the future research on noncovalently modified CNTs-based ORR catalysts is also predicted.
