An academic paper on positive electrode active materials for magnesium rechargeable batteries by our former student Dr. Jonghyun Han et al. was selected as an supplementary cover art of The Journal of Physical Chemistry C.

An academic paper on positive electrode active materials for magnesium rechargeable batteries by our former student Dr. Jonghyun Han et al. has been accepted for publication in The Journal of Physical Chemistry C.

The mechanism of catalytic activity of positive electrode active materials for magnesium rechargeable batteries for oxidative and reductive decomposition reactions of electrolyte was comprehensively explained by a combination of experiments and calculations. Based on this mechanism, we proposed one of the design guidelines for positive electrode active materials. This is the result of joint research with Prof. Ichitsubo at Institute for Materials Research, Tohoku University and Prof. Nakayama at Nagoya Institute of Technology.

An academic paper by our student Mr. Liu Wei et al. on oxygen evolution catalysts has been accepted for publication in Materials Advances.

We have investigated the effect of ions occupying the tetrahedral sites of spinel oxides on the catalytic activity for oxygen evolution reaction. In particular, we found that dissolution of Zn ions occupying the tetrahedral sites leads to cation defects, which facilitates adsorption of reaction intermediates, thereby enhancing the activity. We also showed that a large amount of cation defects leads to structural instability and lower activity.

An academic paper on oxygen evolution catalyst by our student Mr. Wei Liu and graduate Mr. Kodai Kawano was selected as the Inside Back Cover of Small journal.

An academic paper by our student Mr. Liu Wei and a graduate Mr. Kodai Kawano et al. on oxygen evolution catalysts has been accepted for publication in Small.

Various types of highly active oxygen evolution oxide catalysts have been reported. However, most of them dissolve in acidic aqueous solutions due to their oxide nature. In this study, in cooperation with Prof. Ikuya Yamada’s Group at Osaka Metropolitan University, we synthesized a quadruple perovskite ruthenium oxide ACu3Ru4O12 with high stability in acidic aqueous solutions. Furthermore, we changed the valence of the Cu ion by substituting the A-site cation and clarified the correlation with the catalytic activity for the oxygen evolution reaction, and found that the oxygen evolution reaction proceeds with a dual-site mechanism involving both Ru and Cu.
