Nano Twist and Shout: Chiral Nanoantennas Making Water Splitting Cool
Original language description
In the last several years, spin polarization of electrons has been reported as a promising method of improving oxygen evolution reaction (OER). Here, we report the development of a system of hybrid multilayer materials with a chiral property for light-assisted water splitting. The chiral electrodes were prepared via a thin patterned metal film, with a dielectric layer. A layer of redox-active was deposited on the top of prepared structure. The resulting samples were characterized at each step of their preparation using SEM-EDX methods. It is hypothesized that electron spin polarization suppresses the formation of hydrogen peroxide and promote the formation of triplet state of O2 during OER. This assumption was confirmed via electrochemical measurements, particularly using linear sweep voltammetry and chronoamperometry. During the experiments, we found a correlation between the OER efficiency and the electrode chirality.
