Chiral-Induced Spin Selectivity in Electrochemical CO₂RR, OER, and HER
This project explores chiral-induced spin selectivity (CISS) as a strategy to control reaction pathways and enhance performance in key electrochemical reactions, including CO₂ reduction (CO₂RR), oxygen evolution (OER), and hydrogen evolution (HER). Chiral materials can generate spin-polarized electrons without external magnetic fields, enabling selective control over spin-dependent electron transfer processes at electrochemical interfaces.
By integrating chiral molecules and chiral nanostructured catalysts into electrochemical systems, we investigate how spin polarization influences reaction kinetics, intermediate stabilization, and product selectivity. In CO₂RR, spin-polarized electron transfer is expected to suppress undesired reaction pathways and improve selectivity toward value-added carbon products. For OER and HER, where spin states of reactants and intermediates play a critical role, CISS-driven spin control offers a promising route to reduce overpotentials and enhance catalytic efficiency.
This research combines electrochemical characterization, spin-sensitive measurements, and catalyst design to establish fundamental correlations between chirality, spin polarization, and catalytic activity. The outcomes aim to provide new mechanistic insights into spin-dependent electrocatalysis and to advance the development of energy-efficient and selective electrochemical systems for sustainable energy conversion.
