Escalation of CO₂ concentration in atmosphere worsens the effect of global warming. CO₂ conversion to fuel using photocatalytic process is one of the solutions to reduce the gasses. Reduced Graphene Oxide (rGO) has spesific surface area, high electron conductivity and adsorption capacity so that it’s potentially  applied in photocatalytic processes. CuO is a semiconductor which has high spesific surface area, high abundance and low cost. rGO which combined with semiconductor has an ability to store and conduct elektron through transfer electron process that plays most important role in photocatalytic reaction activity. This study uses rGO/CuO composite to convert CO₂ to methanol by photocatalytic process material to convert CO₂into methanol. rGO and CuO were linked by amonia in various weight ratio (1 %, 2%, and 4 %).  Photocatalytic of rGO/CuO is explored for reduction of CO₂ into methanol under the visible light irradiation with irriadiationtime 2 h, 4 h, and 6 h. rGO/CuO material is characterized using XRD, SEM, BET and UV-Vis, while the amount of produced CO₂ is examined using GC-MS.  rGO/CuO composites with ratio 1 % and irradiation time 2 h exhibited good photocatalytic activity owing high yield methanol.  rGO/CuO composites are potential materials to convert CO₂ into methanol.
