제목 Cu2O core/g-C3N4 shell for CO2 photo-conversion methanol synthesis
초록 Research of CO2 fuel conversion selectivity have been critical issue because products are mixed during CO2 photo-conversion. Some of metal oxide catalysts to improve conversion selectivity have been available for different products. In this study, Cu2O core/g-C3N4 shell on surface of vertical TiO2 NRs were grown by polyol method, chemical bath deposition and oxidation after electrodeposition using FTO glass. Grown heterojunction nano-structures were confirmed by means of both FESEM (field emission scanning electron microscope) and TEM (transmission electron microscope). 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 evaluated by GC-MS (gas chromatography-mass spectrometer) and stability of Cu2O core/g-C3N4 shell composite also was studied.
