| contents | A Monodisperse, End‐Capped Ru(bda) Oligomer with Outstanding Performance in Heterogeneous Electrochemical Water Oxidation Tilman Schneider Florian Seebauer Florian Beuerle Frank Würthner Advanced Materials Technologies AbstractWater oxidation catalysis is a key step for sustainable fuel production by water splitting into hydrogen and oxygen. The synthesis of a novel coordination oligomer based on four Ru(bda) (bda = 2,2′‐bipyridine‐6,6′‐dicarboxylate) centers, three 4,4′‐bipyridine (4,4′‐bpy) linkers, and two 4‐picoline (4‐pic) end caps is reported. The monodispersity of this tetranuclear compound is characterized by NMR techniques. Heterogeneous electrochemical water oxidation after immobilization on multi‐walled carbon nanotubes (MWCNTs) shows catalytic performance unprecedented for this compound class, with a turnover frequency (TOF) of 133 s−1 and a turnover number (TON) of 4.89 × 106, at a current density of 43.8 mA cm−2 and a potential of 1.45 V versus normal hydrogen electrode (NHE). 10.1002/admt.202301721 http://creativecommons.org/licenses/by/4.0/ |
