| Abstract |
Ongoing research of the precise CO2 to fuel conversion selectivity became important issue because products are mixed during CO2 reduction. In order to improve conversion selectivity, some of metal oxide catalysts are available for different products. In this study, InP was vertically grown on FTO glass by chemical bath deposition instead of dominant chemical vapour deposition. And grown InP nanorods were confirmed by means of both FESEM (field emission scanning electron microscope) and TEM (transmission electron microscope). Cu2O NPs were comparatively studied by two different methods that of electrodeposition/oxidation process and SILAR (successive ionic layer adsorption and deposition process process). CO2 to CH3OH conversion selectivity 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 NMR (nuclear magnetic resonance) and raman spectroscope to identify inside solution composition. Quantitative measurement of CH3OH was also conducted by HPLC (high performance liquid chromatography).
