Graphene was synthesized by the chemical vapor deposition (CVD). Initially ratios of Ar, H2 and CH4 gases were optimized to get a single layer graphene by CVD. Raman characterizations showed that the optimized synthesis conditions provided I2D/IG ratio as 3 that this ratio indicated the formation of the single layer graphene. The synthesized single layer graphene was mixed with melamine at the certain ratios to obtain the graphene/graphitic-C3N4 (g-C3N4) semiconductor composites. All the synthesized composites were prepared as the photo-electrode to be used in the photo-assisted charging of the lithium-ion oxygen battery. The photo-current levels produced by the photo-electrodes were determined by the linear sweep voltammetry technique.
