Influence of Preparation Conditions of Coated TiO2 Film on CO2 Reforming Performance

Reforming Performance and Visible Light Responsibility of Cr-Doped Prepared by Sol-Gel and Dip-Coating Method

“…Since the product of CO 2 reforming is only CO in this experiment, it is thought that the reduction effect of TiO 2 is not so significant according to the reaction scheme [1,2,4,8,10,42,43] as shown in Figure 7. From Figure 7, more electron and proton are necessary to produce hydrocarbons like CH 4 , C 2 H 4 , and C 2 H 6 .…”

“…When the reduction effect of TiO 2 is promoted, the concentration of CO which is a preproduct to the hydrocarbons is also increased. According to the previous studies [40][41][42][43], the increase in N is effective to promote the reduction performance of TiO 2 photocatalyst due to increase in the amount of TiO 2 . Under larger N condition, many electrons are produced by photocatalytic reaction due to the promotion of reduction performance of TiO 2 .…”

“…Although many studies to extend the photoresponse extension of TiO 2 to the visible spectrum were reported as described above, there are only a few reports on promoting the CO 2 reforming performance using TiO 2 [39]. In our former papers [40][41][42][43], we reported the investigation on the effect of TiO 2 thin film preparation conditions for sol-gel and dip-coating method by the CO 2 reforming experiment though it was carried out under the condition of illuminating UV light only.…”

Effect of Preparation Condition of Ti Film and Experimental Condition on C Reduction Performance of Ti Photocatalyst Membrane Reactor

“…Therefore, it is thought that the largest amount of TiO 2 film is coated on gas separation membrane under the condition of RS = 0.66 mm/s. According to the reaction scheme in this study as shown in Figure 11 [1,5,6,11,16,[26][27][28][29], the number of electron and hydrogen ions (H + ) decides the type of product in the reaction. In this experiment, CH 4 , C 2 H 4 , and the other hydrocarbons were not detected by gas chromatograph, due to less H + in the reaction.…”

Effect of Fe Loading Condition and Reductants on CO2 Reduction Performance with Fe/TiO2 Photocatalyst

“…Generally speaking, H 2 O is used as a reductant for CO 2 reduction by photocatalyst according to some review papers [20][21][22][23]. The reaction scheme of CO 2 reduction with H 2 O is as follows [4,[24][25][26].…”
