• graphene and silicene remains an experimental challenge [10]. Other single atom thick, 2D membranes, such as pristine g-C3N4 and graphdiyne, have been reported for hydrogen purification but are not suitable for helium separation due to their large pores [8]. Therefore, the development of new, pristine, two

• interestingly, valence electrons may be directly excited from graphene into the CB of TiO2 under visible light illumination, so that graphene may be used as a photosensitizer. The authors also investigated the graphene–g-C3N4 interface by hybrid functional DFT methods and found a band gap (around 70 meV
