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 H 2 storage. The as‐prepared samples show similar belt‐like morphologies, chemical compositions, surface areas, and pore volumes. The difference in H 2 sorption behavior for the materials reveals that a narrower pore width likely favors H 2 uptake at a low pressure range, while an increased proportion of BN domains in the materials may be beneficial to enhance H 2 uptake at elevated pressures at 77 K.
