Cation-swapped homogeneous nanoparticles in perovskite oxides for high power density

Exsolution is attractive for the preparation of catalytically active metal nanoparticles, but versatility is limited. Here the authors report a technique for selective exsolution through topotactic ion exchange, leading to an electrocatalyst for a solid oxide fuel cell with enhanced performance.
