Formic Acid Acting as an Efficient Oxygen Scavenger in Four-Electron Reduction of Oxygen Catalyzed by a Heterodinuclear Iridium-Ruthenium Complex in Water
A heterodinuclear iridium ruthenium complex [Ir-III(Cp*)(H2O)(bpm)Ru-II(bpy(2)](SO4)(2) (Cp* = eta(5)-pentamethyl-cyclopentadienyl, bpm = 2,2'-bipyrimidine, bpy = 2,2'-bipyridine) acts as an effective catalyst for removal of dissolved O-2 by the four-electron reduction of O-2 with formic acid in water at an ambient temperature.
