Nowadays, Carbon Capture and Conversion (CCC) method is one of the alternative solutions in carbon management. The reduced graphene oxide-Titanium (rGO-TiO₂) composites are the CCC material that will capture the carbon dioxide (CO₂) and convert it into hydrocarbon fuels such as methane. The effect of synthesizing method into crystallinity growth and the band gap will be studied in this research work.Therefore, the rGO-TiO₂ will be synthesized via solvothermal and hydrothermal methods and then will be characterized via 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 methods affected the crystallinity growth and its band gap. The rGO-TiO₂ synthesized via modified hydrothermal method shows the lowest crystallite size and band gap compared to other samples. It will indirectly affect the photogenerated electrons on TiO₂ to rGO better compared to rGO-TiO₂ synthesized via solvothermal. The green synthesis method which requires a low equipment cost and simple experimental steps is the contribution of this research finding.
