Query: Enhanced H$_2$ storage capacity of the bilayer hexagonal Boron
  Nitride(h-BN) incorporating Van der Waals interaction under applied external
  electric field   Lightweight 2D materials due to its large surface area are being studied for
its hydrogen storage applications. The characteristics of hydrogen adsorption
on the electric field-induced h-BN bilayer were investigated. The overall
storage capacity of the bilayer is 6.7 wt% from our theoretical calculation
with E ads of 0.308 eV/H$_2$. The desorption temperature for H$_2$ molecules
from the h-BN bilayer system in the absence of an external electric field is
243 K. With the introduction of an external electric field, the E$_{\rm ads}$
lies in the range 0.311-0.918 eV/H$_2$ with a desorption temperature of 245-725
K. The charge transfer analysis reveals that 0.001-0.008 |e| of electronic
charge transfer between the h-BN bilayer and H$_2$ molecules. Henceforth, the
adsorption mechanism is through a weak Van der waals interaction. Our results
show that the external electric field enhances the average adsorption energy as
well as the desorption temperature and thus making the h-BN bilayer a promising
candidate for hydrogen storage.
