Abstract:
Controlling chirality in inorganic nanostructures offers a powerful route to tailoring their electronic and catalytic functions. Here, we demonstrate that the chiral morphology of metallic 1T-MoS2 nanosheets can be precisely tuned to modulate spin-dependent properties via the chirality-induced spin-selectivity (CISS) effect. By systematically varying the handedness and morphology of the nanosheets, we reveal a direct correlation among chiral architecture, spin polarization, and electrocatalytic activity for oxygen redox reactions. Chiral 1T-MoS2 catalysts exhibit remarkably enhanced kinetics and reduced reaction overpotentials for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) with performance gains directly linked to spin-polarized charge transport. These findings illustrate the advantages of tuning the chiral morphology in transition-metal dichalcogenide nanostructures to tailor spin-dependent properties for advanced catalysis and energy conversion applications.

Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
