Abstract
Hydrogen boride (HB) sheets have recently been synthesized as new two-dimensional materials composed of boron and hydrogen. This study reports a new role of HB sheets as reductants. Ultraviolet–visible spectroscopy was undertaken for a mixture of HB sheets with several metal ions in solution. The sheets had a redox potential between −0.277 and −0.257 V versus standard hydrogen electrode (SHE). We subsequently demonstrated the facile formation of HB sheet nanocomposites with metal nanoparticles using this reduction property. Herein, we report a new role of HB sheets as reductants. Ultraviolet–visible spectroscopy was conducted for a mixture of HB sheets with several metal ions in solution. The redox potential of HB sheets was between −0.277 and −0.257 V versus SHE. We then demonstrated the facile formation of HB sheet nanocomposites with metal nanoparticles using its reducing property.
