Boosting the Selectivity in Oxygen Electrocatalysis Using Chiral Nanoparticles as Electron-Spin Filters

Controlling the electron spin of oxygen-containing intermediates is crucial for efficient oxygen electrocatalysis toward clean energy technologies such as fuel cells and water electrolysis. Current strategies for controlling the electron spins rely mainly on tuning the chemical structure of the oxygen electrocatalyst, which is often hardly achieved for metal and oxide electrocatalysts. The chiral-induced spin selectivity (CISS) effect, a significant discovery in chiral spintronics, represents an alternative approach for tuning the spin selectivity of oxygen electrocatalysts. Here we demonstrate the use of intrinsic chiral nanoparticles as electron-spin filters to tune the selectivity in oxygen electrocatalytic…
