Cobalt porphyrin electrode films for electrocatalytic water oxidation.
Catalysts play very important roles in artificial photosynthesis for solar energy conversion. In this present study, two water-insoluble cobalt porphyrin complexes, cobalt(II) meso-tetraphenylporphyrin (CoP-1) and cobalt(II) 5,10,15,20-tetrakis-(4-bromophenyl)porphyrin (CoP-2), were synthesized and coated as thin films on the FTO working electrode. The films showed good activities for electroca...
متن کاملInterrogation of electrocatalytic water oxidation mediated by a cobalt complex.
Examination of the aqueous electrochemistry of a Co(II) complex bearing a pentadentate ligand suggests that the catalytic current corresponding to water oxidation is molecular in origin, and does not emanate exclusively from Co-oxide phases formed in situ.
متن کاملElectrocatalytic water oxidation by Cu(II) complexes with branched peptides.
Two mononuclear Cu(II) complexes with tetrapeptides incorporating a L-2,3-diaminopropionic acid (dap) branching unit are reported to undergo PCET and catalyse water oxidation. C-terminal His extension of dap (L = 2GH) instead of Gly (L = 3G) lowers the pKa for Cu(III)H-2L (9.36 vs. 9.98) and improves the TOF at pH 11 (53 vs. 24 s(-1)).
متن کاملElectrocatalytic oxidation of water observed on a nano-gold/palladium electrode.
New and unknown electrocatalytic oxidation of water was found to occur on a nano-gold attached palladium electrode. Since the oxidation potential was negative enough to that of well-known normal oxidation of water to form O2, the direct use of water as a fuel, instead of alcohols, might be possible using the nano-gold/palladium electrode.
متن کاملMechanistic Parameters of Electrocatalytic Water Oxidation on LiMn2O4 in Comparison to Natural Photosynthesis
Targeted improvement of the low efficiency of water oxidation during the oxygen evolution reaction (OER) is severely hindered by insufficient knowledge of the electrocatalytic mechanism on heterogeneous surfaces. We chose LiMn2 O4 as a model system for mechanistic investigations as it shares the cubane structure with the active site of photosystem II and the valence of Mn3.5+ with the dark-stab...
