Abstract
Hydrogen boride sheets (HB sheets) were efficiently synthesized through wet chemical exfoliation of bulk MgB2. High production yield of HB sheets over 50% was achieved in 2 h reaction time by the addition of formic acid into the organic media with the presence of proton-exchange resin. Synthesized HB sheets exhibited two-dimensional nanostructure with sp2-like bonds. Hydrogen boride sheets (HB sheets) were efficiently synthesized through wet chemical exfoliation of bulk MgB2.
