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 controlling spins rely mainly on tuning chemical structure electrocatalyst, which often hardly achieved metal oxide electrocatalysts. The chiral-induced selectivity (CISS) effect, a significant discovery in chiral spintronics, represents an alternative approach Here we demonstrate use intrinsic nanoparticles electron-spin filters to tune electrocatalytic reactions. Chiral Au with concave vortex cube were employed substrate, exhibiting highly tunable optical chirality intriguing CISS-like effect. As model systems, catalytically active components Pt or Ni(OH)2 are overgrown onto construct hybrid Remarkably, both cases show chirality-dependent activities over reduction/evolution reactions, respectively. insights gained from this work not only shed light underlying mechanisms dictating CISS-enhanced by but also provide important knowledge framework that guides rational design electrocatalysts electrocatalysis.
