Enhancement of electrocatalytic oxygen evolution by chiral molecular functionalization of hybrid 2D electrodes

open access: yesNature Communications, 2022
While solar-to-fuel catalysis requires the careful transfer of electrons, there are still challenges understanding how electron spin contributes to reactivity. Here, authors employ chiral fused thiadiazole-helicenes to control spin polarization in oxygen
