Abstract
Nowadays, Carbon Capture and Conversion (CCC) method is one of the al ternative solutions in carbon management. The reduced graphene oxide-Titanium ( rGO-TiO 2 ) composites are the CCC material that will capture the carbon dioxide (CO 2 ) and convert it into hydrocarbon fuels such as methane. The effect of synthesiz ing method into crystallinity growth and the band gap will be stud ied in this research work. Therefore, the rGO-TiO 2 will be synthesize d via solvothermal and hydrothermal methods and then will be characterize d 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 method s affect ed the crystallinity growth and its band gap. The rGO-TiO 2 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 TiO 2 to rGO better compared to rGO-TiO 2 synthesized via solvothermal. The green synthesis method which require s a low equipment cost and simple experimental steps is the contribution of this research finding.
