Here, we report the synthesis of potassium\u2010doped borophane (BH) nanosheets, which serve as a high\u2010capacity, reversible hydrogen storage platform and metal\u2010free reducing agent. Through selective hydride transfer, the BH sheet efficiently converted levulinic acid (LA) to \u03b3\u2010valerolactone (GVL) under mild reaction conditions. Density functional theory (DFT) predicts a theoretical hydrogen content of 4.2 wt.% for the potassium\u2010doped BH sheet. Remarkably, the dehydrogenated BH sheets can be partially regenerated under 50\u00a0bar H\n                    <jats:sub>2<\/jats:sub>\n                    , demonstrating reversible hydrogen storage.
