Molecular Cobalt Clusters as Precursors of Distinct Active Species in Electrochemical, Photochemical, and Photoelectrochemical Water Oxidation Reactions in Phosphate Electrolytes

Three cobalt model molecular compounds, Co‐cubane ([Co4(µ3‐O)4(µ‐OAc)4py4]), Co‐trimer ([Co3(μ3‐O)(µ‐OAc)6py3]PF6), and Co‐dimer ([Co2(μ‐OH)2(µ‐OAc)(OAc)2py4]PF6), are investigated as water oxidation reaction (WOR) catalysts, using electrochemical, photochemical, and photoelectrochemical methodologi...
