Formation of titania-silica mixed oxides in solvent mixtures and their influences for the photocatalytic CO2 conversion to hydrocarbon |
| 초록 |
Composite photocatalyst based on TiO2-SiO2 responsive to solar light were synthesized in various polar and nonpolar organic solvent mixtures materials. The synthesis of composite material was performed using Sol-Gel method. The materials prepared were characterized including XRD, UV Vis spectroscopy, BET surface area, TEM and XPS. The TiO2-SiO2 mixed oxide photocatalysts prepared in the presence of nonpolar aromatic solvents such as xylene, toluene or benzene along with ethanol show high surface area, huge mesoporosity, and enormous pore volume compared to the materials conventionally synthesized in a mixture of ethanol and hexane. The TiO2-SiO2 mixed oxide catalyst prepared in benzene along with ethanol yield 21 ppm/hour of methane production which was maximum as compared to other samples revealing the effect of aromatic nonpolar solvents tuning the textural properties of photocatalysts. |
