Chiral 2D flakes with single atoms inclusion for spin-controlled oxygen evolution

Original language description

Spin control represents an interesting avenue in modern electrochemistry, with the ability to tune the state of reaction intermediates and the overall reaction selectivity and yield. One of the ways to achieve the reaction spin control is the preparation of specific electrodes through the utilization of the so-called chiral-induced spin selectivity phenomenon (CISS). This approach is based on the utilization of chiral coatings on the surface of redox-active materials, which allow one to align the spin of transited electrons, but limits the available current densities and electrode stability. In this work, the realization of the CISS phenomenon with the implementation of intrinsically chiral 2D flakes of MoS&lt;inf&gt;2&lt;/inf&gt; doped with single Ni atoms is proposed for the first time. The created material was applied to an oxygen evolution reaction (OER) performed under alkaline conditions. The single-atom catalyst provides the material redox activity, while the flakes chirality ensures the alignment of the spins of transited electrons. We reached a significant enhancement of the OER kinetics and suppressed hydrogen peroxide formation. The utilization of the proposed chiral materials allows us to perform OER experiments at a relatively high current density and significantly improve the electrode stability. © 2025 The Authors
