Synthetic models of oxygen evolving complex (OEC) are used not only to gain better understanding of the mechanism and the roles of cofactors for water oxidation in photosynthesis, but also as water oxidation catalysts to realize artificial photosynthesis, which is anticipated as a promising solar fuel production system. However, although much attention has been paid to the composition and structure of active sites for development of heterogeneous OEC models, the cofactors, which are essential for water oxidation by the photosynthetic OEC, remain little studied. The high activity of CoO(OH) nanoparticles for electrocatalytic water oxidation is shown to be induced by a CO cofactor. The possibility of CO ions acting as proton acceptors for O-O bond formation based on the proton-concerted oxygen atom transfer mechanism is proposed. The O-O bond formation is supposed to be accelerated due to effective proton acceptance by adjacent CO ions coordinated on the Co center in the intermediate, which is consistent with Michaelis-Menten-type kinetics and the significant H/D isotope effect observed in electrocatalysis.

“…Some publications dealing with EPD films report the dispersion of several particles in acetone. In these works, oxides (such as SiO 2 ) in which acid sites predominate at the surface develop a negative charge in acetone dispersions [19,33,35,51,60]. Since the solvent acts as donor, electron transfer occurs from the liquid to the solid.…”

Electrophoretic Deposition (EPD) performance strongly depends on the particles surface chemistry and the ability to manipulate surface-liquid interfaces. In this study an extensive investigation of YBCO suspension in dry acetone, acetone-water mixtures and acetone-iodine is reported. Chemical instability of YBCO particles determines their colloidal behaviour. Charging mechanism of particles has therefore had to be deeply investigated for complete dispersion understanding. In order to determine the conditions of the YBCO suspension stability, measurements of pH, conductivity, zeta-potential, settling tests, modelling of the particle networks and electrophoretic deposition were done. The influence of the water and iodine concentration, and their role as stabilizers was evaluated. Based on experimental results, pair particle potentials were calculated and then different charging mechanisms of YBCO surfaces in acetone were proposed.

In order to study anode effects in Cu electroplating, we investigated the characteristics of the Cu films electrodeposited on Cu seed layer and the surface change of anodes, by using Cu (soluble) and Pt (insoluble) anodes. For the case of Cu anode, the brownish passivation layer was formed on the surface of Cu anode, and this was mainly composed of by-products which was formed by reaction of impurities in electrolyte with copper anode. In use of Pt anode, the O 2 bubbles on the anode surface were occurred. The current density in bath for the case of Cu anode was larger than that of Pt anode and increased after 300 s of plating time had elapsed. In formation of the electroplated Cu films, the deposition rate of Cu films electroplated by using Cu anode was larger and the density of film plated by using Cu anode was higher than those by Pt anode.
