The activity of Pt towards oxygen reduction reaction (ORR) can be enhanced by alloying it with secondary metals. They can be grouped into three different classes: alloys, bimetallics and intermetallics. Although alloys and bimetallics exhibit enhanced performance, often they are limited by metal dissolution and resulted in poor durability. This invokes the need on the development of ordered intermetallics. In this minireview we comprehensively present the recent progress and developments of Pt X alloys and intermetallics towards ORR. Additionally, major technical challenges and possible future research directions to overcome these challenges are discussed to facilitate further research in this area.
通过将铂(Pt)与其他金属合金化,可以提高其对氧还原反应(ORR)的活性。这些合金可分为三类:合金、双金属和金属间化合物。尽管合金和双金属表现出增强的性能,但它们往往受到金属溶解的限制,导致耐久性较差。这就引发了对有序金属间化合物的需求。在本综述中,我们全面介绍了Pt-X合金和金属间化合物在ORR方面的最新进展。此外,还讨论了主要技术挑战以及克服这些挑战的可能未来研究方向,以促进该领域的进一步研究。
