Electron spin selective electrodes for oxygen evolution reaction Carlos Mingoes 1 Ana Sobrido 1 , Bob Schroeder 2 1 Queen Mary University of London, UK, 2 University College London, UK The CISS effect details that an electron traversing a chiral molecule does so spin selectively, essentially making said molecule an electron filter. 1 As such, this effect could be used to control reaction pathways to minimise undesired products and boost desired ones. This has been demonstrated for oxygen evolution reaction (OER), whereby induced spin correlation, drives the reaction to favour oxygen formation over hydrogen peroxide formation. 2,3 The adsorption of chiral molecules on a surface, spin polarises the interface, thus functionalising nano-catalysts for OER with chiral molecules could be useful for improving catalytic activity. 4 Here in, I present nanocatalysts exhitibing spin selective OER when when immobilised on self-assembled monolayers of chiral molecules.
