Researchers at Tokyo Institute of Technology, University of Tsukuba, and colleagues in Japan have reported a promising hydrogen carrier in the form of hydrogen boride nanosheets. This two-dimensional material, which is not yet well studied, could eventually be used for lightweight, high-capacity hydrogen storage materials with good safety profiles.

Innovative nanosheets made from equal parts of and boron have a greater capacity to store and release hydrogen compared with conventional metal-based materials.

This finding by researchers at Tokyo Institute of Technology (Tokyo Tech), the University of Tsukuba, Kochi University of Technology and the University of Tokyo reinforces the view that hydrogen boride nanosheets (HB sheets) could go beyond graphene as a nano-sized multifunctional material.

Their study, published in Nature Communications, found that hydrogen can be released in significant amounts (up to eight weight percent) from HB sheets under , even under mild conditions—that is, at ambient room temperature and pressure.
