Abstract
The object of the present invention is to provide an excellent method for storing and transporting hydrogen. The object can be solved by a structure comprising boron, hydrogen, and oxygen, that has B—H—B bonds, B—H bonds, and B—OH bonds, and in the measurement of FT-IR spectra, the following formulas are satisfied: (1) 0.80≤a/c≤0.96, and (2) 0.95≤b/c≤1.12, wherein when the baseline is defined as 100%, a is the transmittance at 1400 cm−1 in the FT-IR spectrum, b is the transmittance at 2500 cm−1 in the FT-IR spectrum, and c is the transmittance at 3200 cm−1 in the FT-IR spectrum.
