Two-dimensional hydrogen boride (HB) sheets prepared via the ion-exchange reaction from magnesium diboride (MgB2) are known to possess several intriguing properties for a wide range of applications; however, previous reports have shown that using this method contain small amounts reactive components, making them unsuitable certain applications. Therefore, developing preparing HB exhibit long-term stability and do not species is essential. In study, we developed an effective treatment...

Abstract Hydrogen boride (HB), a freestanding 2D hydrogenated‐borophene (borophane) polymorph, is synthesized via ion exchange. HB sheets with B/H atomic ratio of 1.0 are confirmed to contain three‐center–two‐electron B–H–B bonds and two‐center–two‐electron terminal B–H bonds. The optical properties expected be tunable by changing the BHB/BH bond ratio, which alters electronic structure sheets; however, this not yet achieved. This study demonstrates that controlling in possible without...

Hydrogen boride (HB) sheets are two-dimensional materials comprising a negatively charged hexagonal boron network and positively hydrogen atoms with stoichiometric ratio of 1:1. Herein, we report the spontaneous formation highly dispersed Ni nanoclusters on HB sheets. The reduction reaction ions by was monitored in-situ measurements an ultraviolet-visible spectrometer. Acetonitrile solutions complexes acetonitrile dispersions were mixed in several molar ratios (the HB:Ni varied from 100:0.5...

Photoinduced H2 Release In article 2300414, Masahiro Miyauchi, Takahiro Kondo, and co-workers confirmed hydrogen boride (HB) sheets with a B/H atomic ratio of 1.0, freestanding 2D hydrogenated-borophene (borophane) polymorph, to contain three-center–two-electron B–H–B bonds two-center–two-electron terminal B–H bonds. Increasing the BHB/BH bond HB enhances luminescence intensity, whereas reducing it photoinduced release rate under UV irradiation.

In this study, deuterium boride (DB) nanosheets were synthesized as deuterated borophane through the ion exchange of magnesium cations in diboride with deuterons from a deuterium-type ion-exchange resin acetonitrile. The Fourier-transform infrared absorption spectrum DB exhibited clear isotope effects, namely shift peak B-H stretching vibrational mode to lower wavenumber. Temperature-programmed desorption (TPD) mixture and hydrogen (HB) yielded more intense hydrogen-deuterium (HD) signal compared H
