Gold-nanoparticle-modified TiO2 nanowires for plasmon-enhanced photocatalytic CO2 reduction with H2 under visible light irradiation

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

“…Pt-doped TiO 2 catalyst revealed enhanced activity for CO 2 reduction to CH 4 [22]. 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].…”

A Review of Direct Z‐Scheme Photocatalysts

“…To this end, much research has been devoted to searching for new technologies for the reduction of CO 2 , for example biological conversion, electrocatalysis, photocatalysis, and photothermal catalysis . Among them, photocatalytic CO 2 reduction into valuable chemical fuels such as CH 4 , CH 3 OH, HCOOH, and CH 2 O has received great attention because it can alleviate the current dependence on fossil fuels of human society, as well as reducing the CO 2 concentration in the atmosphere . Notably, hydrocarbon fuels such as CH 4 or CH 3 OH have a higher energy density than H 2 , making them easier for energy storage and more suitable for practical applications.…”

TiO2 Processed by pressurized hot solvents as a novel photocatalyst for photocatalytic reduction of carbon dioxide

“…These drawbacks significantly reduce photoconversion in the presence of TiO 2 . Surface heterojunction and surface modifications are two possibilities how to increase visible light absorption ability and also slow down the recombination rate [17][18][19][20][21][22][23][24].…”
