The intensive studies towards graphene have stimulated recently huge interests on graphene-like 2D layered nanomaterials. The relaxed crystalline water structure obtained from the modified ice {\it Ih} crystal symmetry shows $P_{6/mmc}$ space group sheet consisted of Oxygen atoms. The DFT calculations implemented by Abinit package show for Oxygen honeycomb lattice layer the O-O bond length of 2.612 \AA, the lattice constant of 4.523 \AA. The application of the graphene tight-binding model unveils the value of 2.71 eV absorption peak which is well-fitted with the experiment data.
