摘要

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.
