Abstract
A two-dimensional hydrogen boride-containing sheet of the present invention has a two-dimensional network that consists of (HB)n (n≥4).
Claims6
A two-dimensional hydrogen boride-containing sheet, comprising:
- a two-dimensional network that consists of (HB)n (n≥4), wherein
- in a X-ray photoelectron spectroscopy, a spectrum showing a peak attributable to B1s of a negatively charged boron in the vicinity of approximately 188 eV and no peak attributable to magnesium is obtained,
- in an electron energy loss spectroscopy, a spectrum showing a peak attributable to sp2 structure of boron at approximately 191 eV is obtained, and
- a molar ratio of boron to hydrogen determined from thermal desorption spectroscopy and measurement of mass of the two-dimensional hydrogen boride-containing sheet before and after heating the two-dimensional hydrogen boride-containing sheet is 1:1.
1 more element
A production method for a two-dimensional boron compound-containing sheet, comprising:
- a step of mixing, in a polar organic solvent, metal diboride having an MB2-type structure (where M is at least one selected from the group consisting of Al, Mg, Ta, Zr, Re, Cr, Ti, and V), with an ion exchange resin in which ions exchangeable with metal ions constituting the metal diboride are coordinated.
