title = "Metal-doped photocatalysts to reduce carbon dioxide in ethanolamine solution for methane production",
abstract = "Photocatalytic reduction of carbon dioxide (CO 2) to form valuable energy source of methane (CH 4) in the ethanolamine (MEA) solution is investigated in this study. The TiO 2 photocatalysts were prepared by doping with nano-sized metals (Fe, Zn, Mn, Ce) via the co-precipitation method. The photocatalytic reduction process was performed in the MEA solution because the MEA absorption is one of the most popular methods for CO 2 greenhouse gas capture from flue gas streams. And it is intended to integrate the CO 2 capture and utilization into one process. The tests were performed with the UV light source of 9W and 365 nm. The light intensity of 6.3 mW/cm 2 was measured at the center point between the UV light source and the outer glass of the reactor. The 5 hours test results showed the methane yield followed the order of Ce-TiO 2 > Mn-TiO 2 > Zn-TiO 2 > Fe-TiO 2. Tests were also evaluated with a solar light concentrator, and it has been proved that it is possible to produce CH 4 under solar light without the addition of any external energy source.",
