Boron Incorporation Induces Lattice Expansion in Platinum Nanoparticles for Enhanced Oxygen Reduction Reaction.
The oxygen reduction reaction (ORR) is a key cathodic process in zinc-air batteries, while its sluggish kinetics and the limited stability of Pt nanoparticles constrain practical performance. Achieving high activity, selectivity, and stability while minimizing Pt loading remains a key objective in electrocatalyst desig...
