Reduction of CO2 by adsorption and reaction on surface of TiO2-nitrogen modified photocatalyst

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

“…Recently, studies on CO 2 photochemical reduction by TiO 2 have been carried out from the viewpoint of performance promotion by extending absorption range towards visible region [11][12][13][14][15]. Noble metal doping such as Pt, Pd, Au, and Ag [11], nanocomposite CdS/TiO 2 combining two different band gap photocatalysts [12], N 2 -modified TiO 2 [13], light harvesting complex of green plants assisted Rh-doped TiO 2 [14], and dye-sensitized TiO 2 [15] have been attempted to overcome the shortcomings of pure TiO 2 .…”

They did improve the CO 2 reduction performance; however, the concentrations in the products achieved in all the attempts so far were still low, ranging from 10 ppmV to 1000 ppmV [4][5][6]9] or from 1 μmol/g-cat to 100 μmol/g-cat [7,8,[11][12][13][14][15]. Therefore, a big breakthrough in increasing the concentration level of products is necessary to advance the CO 2 reduction technology in order to make the technology practically useful.…”

Activated Carbons from Molasses as CO2Sorbents

“…CO 2 is one of the main component of post-combustion gases. Lots of different techniques was studied over the years, for example CO 2 conversion to useful products [3]. One of the most popular is carbon capture and storage (CCS).…”

Preparation of Activated Carbon from Beet Molasses and TiO2as the Adsorption of CO2

“…The reduction of CO 2 emissions is dependent on new technological systems as CO 2 conversion to useful chemicals [1] as well as carbon capture and storage (CCS) [2,3]. Hence, to achieve a high level of CO 2 removal, high cost operational technologies are used.…”

“…In addition to determining the proper raw materials, the selection of certain properties of suitable substances is important. TiO 2 was described as photocatalyst for CO 2 conversion [1] and was chosen by us as additive in the preparation of activated carbon.…”
