Abstract
The present invention provides a hydrogen storage and release material including a two-dimensional hydrogen boride-containing sheet including a two-dimensional network containing n(HxBy) (n≥4, 0.001≤x/y≤0.999) having a molar ratio of boron to hydrogen from 1:0.999 to 1:0.001, the molar ratio being determined by thermal desorption spectroscopy, and mass measurement before and after a temperature rise, wherein the hydrogen storage and release material has: peaks derived from B1s of boron at 187.5±1.0 eV and 191.2±1.0 eV to 193±1.0 eV in X-ray photoelectron spectroscopy, and a peak derived from a B—H stretching vibration at from 2400 cm−1 to 2600 cm−1 and also a peak derived from a B—H—B stretching vibration at from 1200 cm−1 to 1800 cm−1 in infrared spectroscopy.
