Effect ofOverlapping Layout ofFe/Tio2on CO2 Reduction withH2andH2O
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
Fe-doped TiO2 (Fe/TiO2) film photocatalyst was prepared by sol-gel dip-coating, and pulse arc plasma process. The netlike glass fiber was used as a base material for the photocatalyst since it had a porous structure. The CO2 reduction performance with H2 and H2O into CO over the Fe/TiO2photocatalyst was investigated.In addition, this study investigated overlapping two Fe/TiO2 coated on netlike glass fiber in order to utilize the light more effectively as well as increase the amount of photocatalyst for CO2 reduction. The characterization of prepared Fe/TiO2 film coated on netlike glass fiber was analyzed by SEM, EPMA, TEM, EDX and EELS.Furthermore, the CO2 reduction performance of the Fe/TiO2 film was tested under a Xe lamp with or without ultraviolet (UV) light, respectively. The results show that the CO2 reduction performance peaks under the condition of CO2/H2/H2O = 1:1:0.5 in both cases with UV light and without UV light illumination.The highest concentration of CO with the Fe/TiO2 overlapped photocatalyst is 1.2 times of that with the single Fe/TiO2photocatalyst. On the other hand, results also show the highest molar quantity of CO per weight of photocatalyst for Fe/TiO2 overlapped is almost half of single Fe/TiO2.
