Abstract
That's below the belt: Porous BCNO materials with tunable ultra-narrow pore widths (0.4-1.1 nm) were prepared and investigated with regard to H2 storage. The as-prepared samples show similar belt-like morphologies, chemical compositions, surface areas, and pore volumes. The difference in H2 sorption behavior for the materials reveals that a narrower pore width likely favors H2 uptake at a low pressure range, while an increased proportion of BN domains in the materials may be beneficial to enhance H2 uptake at elevated pressures at 77 K.
