ABSTRACT: Nowadays, Carbon Capture and Conversion (CCC) methodisone of the alternative solutions in carbon management. The reduced graphene oxide-Titanium(rGO-TiO2) compositesarethe CCC material that will capture the carbon dioxide (CO2) and convert it into hydrocarbon fuelssuch as methane. The effect of synthesizingmethod into crystallinity growth and the band gap will be studiedin this research work.Therefore, the rGO-TiO2will be synthesizedvia solvothermal and hydrothermal methods and then will be characterizedvia XRD and UV-Vis. The temperature and treatment time were fixed in both synthesis methods. The characterization results via XRD and UV-Vis conclude that, the different synthesis methodsaffectedthe crystallinity growth and its band gap. The rGO-TiO2synthesized via modified hydrothermal method shows the lowest crystallite size and band gap compared to other samples. It will indirectly affect the photogenerated electrons on TiO2to rGO better compared to rGO-TiO2synthesized via solvothermal. The green synthesis method which requiresa low equipment cost and simple experimental stepsisthe contribution of this research finding.
