| Abstract: | The photocatalytic reduction of CO2is a hot topic of current researches.A relatively efficient and stable heterogeneous photocatalytic CO2reduction system was established. The hemin as cocatalyst was supported on the surface of TiO2. The change of crystal form of TiO2before and after the loading was compared, and the effect of hemin loading on the reduction was investigated, appropriate solvent was selected, the reaction conditions of the system were optimized. The results showed that, when [Ru(bpy)3]2+was used as photosensitizer, BIH and TEOA were used as sacrificial agent, photocatalytic reduction of CO2was realized in the acetonitrile solution, TONCOof the system was up to 832. |
