| Outline of Final Research Achievements |
In this study, we first investigated the reaction mechanism between MgB2 and water. It was found that ion exchange of magnesium cations of MgB2 with protons occurred followed by the hydrolysis reaction, where a sheet material composed by boron was formed during the process. Next, we attempted to form a new boron-based two-dimensional material consisting only of hydrogen and boron by ion-exchanging the magnesium cations of MgB2 with protons and simultaneously suppressing other reactions. The sheet material was successfully formed under mild conditions of room temperature and atmospheric pressure. The sheet material obtained was composed of only a negatively charged boron with two-dimensional sheet structure and protons, and it was found that the stoichiometric ratio was H: B = 1: 1, so it was named "hydrogen boride sheet".
