Effect of ionic liquid in a pressurized reactor to enhance CO2 photocatalytic reduction at TiO2 modified by gold nanoparticles

Progress and perspectives on 1D nanostructured catalysts applied in photo(electro)catalytic reduction of CO2

“…204 On this basis, Perini et al used a unique pressurized photoreactor with an aqueous solution containing the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate as the medium to study the effect of Au NPs, the ionic liquid and the pressure on the CO 2 RR performance. 205 The loading of Au NPs reduced the band gap of TiO 2 NTs from 3.2 eV to 2.9 eV, as shown in Fig. 15(b).…”

Thermo‐ and Photocatalytic Activation of CO2 in Ionic Liquids Nanodomains

“…Perini et al reported the synergic effect of Au on TiO 2 nanotubes in BMIm•BF 4 IL and obtained CH 3 OH and CH 4 with the yield of 279.6 and 98.8 μmol, respectively. [121] The system needed high pressure (5 bar) and Na 2 SO 3 as a hole scavenger. CO 2 pressure significantly boosted the CH 3 OH generation.…”

Catalytic heterostructured materials for CO2 mitigation and conversion into fuels: a renewable energy approach towards a sustainable environment

“…The Na 2 SO 3 hole scavenger decreased the exciton recombination rate and allowed photogenerated e − to reduce CO 2 . 253 The inorganic and organic pollutants that are present in wastewater are also used as hole scavengers, which help the photogenerated electrons to reduce CO 2 to generate valuable products, while the holes help in the photocatalytic degradation of pollutants, simultaneously, in this approach. 254 However, sufficient studies have not been carried out in this field, and so it can have a wide scope and potential for future research.…”
