Heterogeneous Catalysis
In article number 2308934, Bong‐Joong Kim and co‐workers devise a method to exsolve metal dopants from amorphous perovskite oxides, followed by the crystallization of these oxides through vacuum‐annealing at elevated temperatures. This process extracts all heavily doped Co atoms from SrTiO3, resulting in uniformly distributed, high‐density CoO nanoparticles embedded in the...
Exsolution generates metal nanoparticles anchored within crystalline oxide supports, ensuring efficient exposure, uniform dispersion, and strong nanoparticle–perovskite interactions. Increased doping level in the perovskite is essential for further enhancing performance in renewable energy applications; however, this is constrained by limited surface exsolution, structural instability, and sluggish...
