The inside cover picture depicts how Pt catalysts are able to break the CC bond of the ethanol molecule leading to C 1,ad species, which actually poison the catalysts. Going to more positive potentials makes it possible to remove such species by oxidizing them. The surface an oxophilic particle such as Pt 3 Sn is already covered by OH ad , even at low potentials where ethanol adsorbs. As a consequence, ethanol is easily oxidized to acetic acid, but the route to formation of C 1 oxidized species such as CO 2 is suppressed; see the Full Paper by S. Rojas et al. on page 885 (DOI: 10.1002/celc.201300254 ).
