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

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 11, 2025

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.

Chiral Inorganic Polar BaTiO₃/BaCO₃ Nanohybrids with Spin Selection for Asymmetric Photocatalysis

Nano Letters, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 19, 2024

Chirality-dependent photocatalysis is an emerging domain that leverages unique chiral light–matter interactions for enabling asymmetric catalysis driven by spin polarization induced circularly polarized light selection. Herein, we synthesize inorganic polar BaTiO3/BaCO3 nanohybrids via a hydrothermal method employing glucose as structural inducer. When excited opposite light, the same material exhibits significant catalysis, while enantiomers present preference. More importantly, preferred undergoes reversal with of CD signal. Systematic experimental results demonstrate more photogenerated carriers are generated in semiconductors under suitable irradiation, including spin-polarized electrons, which inhibits recombination electron–hole pairs and promotes activation oxygen molecules into reactive species, thus inducing this photocatalytic feature. This study provides valuable insights development highly efficient polarization-sensitive perovskite nanostructures promising candidates next-generation, multifunctional device applications.
