Effect of Fe Loading Condition and Reductants on CO 2 Reduction Performance with Fe/TiO 2 Photocatalyst
Fe-doped TiO 2 (Fe/TiO 2 ) film photocatalyst was prepared by sol-gel and dip-coating process and pulse arc plasma method. The effect of pulse number on the CO 2 reduction performance with the Fe/TiO 2 was investigated in this study. In addition, the effect of reductants such as H 2 O, H 2 , and NH...

Summary: | Fe-doped TiO
2
(Fe/TiO
2
) film photocatalyst was prepared by sol-gel and dip-coating process and pulse arc plasma method. The effect of pulse number on the CO
2
reduction performance with the Fe/TiO
2
was investigated in this study. In addition, the effect of reductants such as H
2
O, H
2
, and NH
3
/H
2
O on the CO
2
reduction performance with the Fe/TiO
2
photocatalyst was also investigated. The characteristics of the prepared Fe/TiO
2
film coated on a netlike glass fiber which is a base material were analyzed by SEM, EPMA, EDX, and EPMA. Furthermore, the CO
2
reduction performance of the Fe/TiO
2
film was tested under a Xe lamp with or without ultraviolet (UV) light. The results show that the CO
2
reduction performance with the pulse number of 100 is the best with H
2
O and/or H
2
as reductant under UV light illumination, while that with the pulse number of 500 is the best when NH
3
/H
2
O is used as reductant. On the other hand, the CO
2
reduction performance with the pulse number of 500 is the best under every reductant condition without UV light illumination. The highest CO
2
reduction performance with the Fe/TiO
2
is obtained under H
2
+ H
2
O/CO
2
condition, and the best moral ratio of total reductants to CO
2
is 1.5 : 1. |
