Abstract EN
The catalytic activities of carbon-based AgBr nanocomposites (AgBr / CNT, AgBr / GP, AgBr / EG, and AgBr / AC) for CO2 reduction to hydrocarbons under visible light were investigated in this study.
The carbon-based AgBr nanocomposites were prepared on carbon-based supporting materials (CNT, GP, EG, and AC) by the deposition–precipitation method in the presence of cetyltrimethylammonium bromide (CTAB).
The photocatalytic activities of AgBr nanocomposites on different supporting materials (CNT, GP, EG, and AC) were investigated by CO2 reduction yield in the presence of water under visible light (k > 420 nm).
The results of X-ray diffraction (XRD) and transmission electron microscopy (TEM) showed that AgBr nanoparticles were well dispersed on the surface of supporting materials.
AgBr / CNT and AgBr / GP had a relatively higher reduction yield under visible light due to the transfer of photoexcited electrons from the conduction band of well-dispersed AgBr to carbon supporting materials.
In addition, the carbon-based AgBr nanocomposites were stable in the repeated uses under visible light.
The total product yields of carbon-based AgBr nanocomposites after the 5 repeated uses almost remained about 83 % of the first run.
Therefore, carbon-based AgBr nanocomposite is an effective and stable visible-light-driven photocatalyst for CO2 photoreduction.
