The four structural related cobalt-β-diketonate complexes Co(acac)2, Co(acac)2 ⋅ TMEDA, Co(tfac)2 ⋅ TMEDA and Co(hfac)2 ⋅ TMEDA with different degree of fluorination were thermochemically evaluated and used as precursors for the MOCVD growth of cobalt monoxide thin films. The influence of the degree of fluorination of the cobalt precursors on impurities (carbon, nitrogen, and fluorine) in the CoO films and the influence of these impurities on the electrocatalytically activity for the oxygen evolution reaction (OER) in alkaline media was investigated in detail.
