Methane formation from photoreduction of CO2 with water using TiO2 including Ni ingredient

Selective photocatalytic reduction of CO2 by H2O/H2 to CH4 and CH3OH over Cu-promoted In2O3/TiO2 nanocatalyst

“…Au-NPs/TiO 2 with enhanced photoactivity and selectivity prevailed during CO 2 reduction with H 2 to CO [23]. Efficient photocatalytic CO 2 reduction by H 2 O to CH 4 with enhanced selectivity has been reported over NiO/TiO 2 [24]. Instead, indium (In) is well-established as an efficient metal to enhance photoactivity and product selectivity [25,26].…”

Solar cell driven electrochemical process for the reduction of CO 2 to HCOOH on Zn and Sn electrocatalysts

“…This shows high conversion rates toward CO 2 reduction at the applied experimental condition and the maximum efficiency is 400 lmol for 10 min reaction. Methane synthesis using Photo catalytic CO 2 reduction by using nickel ion with TiO 2 electrocatalyst and importance of nickel content on production formation was reported (Kwak et al, 2015). The photo electrochemical reductions of CO 2 in 1 M KHCO 3 electrolyte solutions using iridium based electrocatalyst and a high Faradaic efficiency of 67% was reported (white et al, 2014).…”

“…Studies were examined thermodynamically a two-step solar cycle for CO 2 splitting by using Zn/ZnO and FeO/Fe 3 O 4 redox reactions. Several studies have been done using titanium based electrocatalyst for photo catalytic reduction of carbon dioxide to fuels (Irvine et al, 1990;Adachi and Ohta, 1994;Anpo and Chiba, 1992;Kwak et al, 2015;Kaneco et al, 1999;Ohno et al, 2014;Dey et al, 2004;Liu et al, 2015). The photochemical reduction of CO 2 was investigated on copper based electrocatalyst in various fuel generations Li et al, 2013;Handoko and Tang, 2013;Won et al, 2014;Tseng et al, 2002).…”

Surface modification of layered perovskite Sr2TiO4 for improved CO2 photoreduction with H2O to CH4

“…Of these, TiO 2 is one of the most well-known and widely used materials. In order to improve the optical properties of TiO 2 , it has been combined with various metals to form hybridized composites such as Ag/TiO 2 15 , Pt/TiO 2 16 , Ru/TiO 2 17 , Pd/TiO 2 18 , Ni/TiO 2 19 , Cu/TiO 2 20 , TiO 2 /Cu-TiO 2 21 , CeO 2 -TiO 2 22 , MgO-TiO 2 23 , NiO-In 2 O 3 /TiO 2 24 , CuS x -TiO 2 25 , NiS-TiO 2 26 , In 2 O 3 /TiO 2 27 , TiO 2 /Fe-TiO 2 28 and multi-walled carbon nanotube (MWCNT)@TiO 2 29 in an attempt to reduce the band gap or suppress recombination of photogenerated charge carriers. Also, catalysts having a combination of an organic and metal material such as g-C 3 N 4 30 , Ni 12 P 5 /g-C 3 N 4 31 , Au cluster-NP/C 3 N 4 32 , AgX/g-C 3 N 4 (X = Cl and Br) 33 , RuRu′/Ag/NS-C 3 N 4 34–37 and Co-ZIF 38–41 are being developed.…”
