How to reasonably manage and reutilize the waste expired liquid medicines has always been a puzzling public concern. For this reason, the waste expired medicine of donkey-hide gelatin pulp was recycled by hydrothermal carbonization and hard template for N/S co-doped hard carbon material, and its electrochemical Na-storage performances were also evaluated. The results showed that the resultant N/S co-doped hard carbon material manifested the morphology of hollow nano-spheres with the mean diameter of about 242.3 nm and the shell thickness of about 15 nm; N and S elements evenly distributed in carbon structure by in situ co-doping. Furthermore, N/S co-doped hard carbon also delivered the satisfactory electrochemical Na-storage capacities due to the synergistic effect of the unique hollow nano-spheres with thin shell and N/S co-doping. No doubt, the results would promote the circular economy mode of waste expired medicines.
