Article Synopsis
- A new heterogeneous catalyst using CoO(OH) nanoparticles was tested for electrochemical water oxidation and showed effective performance in a sodium borate solution at a specific voltage.
- HBO and BO ions were identified as crucial cofactors that enhanced the catalytic activity of the CoO(OH) layer, leading to significantly higher current densities than CO ions.
- The study analyzed the catalytic current's dependence on NaBO concentration, revealing important parameters like an affinity constant for cofactors and a maximum current density that outperform previous findings.
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.
