Discovery of nanographene for hydrogen storage solving low reversibility issues
Gagus Ketut Sunnardianto, Yusuf Wicaksono, Halimah Harfah +1
We found good reversibility of hydrogen uptake-release in vacancy-centered hexagonal armchair nanographene (VANG) based on density functional theory calculation. VANG has a triply…
