Ongoing research of the carbon capture and utilization (CCU) became important challenge since the storage of captured carbon technique for CO2 reduction resulted in re-emission. There are several CO2 conversion processes such as a thermal reduction with catalyst, electro-catalytic reduction, biochemical reduction and photocatalytic reduction. Especially photocatalytic CO2 reduction process is analogue to solar water splitting. That is, photocatalysts that were applied for hydrogen evolution could be also used for CO2 reduction. In this study, InP was vertically grown on FTO glass by chemical deposition for visible light absorption and selectivity of methanol synthesis. rGO was synthesized by improved Hummer's method. Microstructures were confirmed by means of both FESEM (field emission scanning electron microscope) and TEM (transmission electron microscope). Its anisotropic growth mechanism was proposed that dissolution and specific precipitation. CO2 to CH3OH conversion test was conducted using three electrode system under visible light that of intensity 100mW/cm2. Products of CO2 reduction was collected by micro-syringe and subsequently transferred to the quartz cuvette involving chemical reagent of CH3OH to coloured solution conversion selectively for qualitative measurement by UV-Vis absorbance. Quantitative measurement of CH3OH was also conducted by GC-MS (gas chromatography-mass spectrometer).
