Abstract

ABSTRACT 2D borophene has long been proposed as a promising hydrogen storage material, but experimental demonstrations remain limited to boron hydride sheets derived from MgB 2 . Here, we report the synthesis of potassium‐doped borophane (BH) nanosheets, which serve as a high‐capacity, reversible hydrogen storage platform and metal‐free reducing agent. Through selective hydride transfer, the BH sheet efficiently converted levulinic acid (LA) to γ‐valerolactone (GVL) under mild reaction conditions. Density functional theory (DFT) predicts a theoretical hydrogen content of 4.2 wt.% for the potassium‐doped BH sheet. Remarkably, the dehydrogenated BH sheets can be partially regenerated under 50 bar H 2 , demonstrating reversible hydrogen storage. This work serves as an experimental validation for alkali‐metal‐modified borophanes acting as a multifunctional material for hydrogen storage and transfer, opening avenues for sustainable energy and other applications.
