Abstract: Considering the aspects of preparation of gold-based photocatalysts and gold photocatalysis, it is worth a mention that it is more complicated issue than in the case of other noble metals due to the gold crystallinity. In this contribution some critical aspects of the gold photocatalysis will be discussed. Au-supported TiO2 and TiO2-ZrO2 photocatalysts and their pristine counterparts were prepared by using the sol-gel process controlled within reverse micelles environment and by impregnation under vacuum. All photocatalysts were characterized by OEA, ICP/MS, N2 physisorption, XRD, TEM/SEAD and UV-Vis. The performance of laboratory-prepared photocatalysts was examined in CO2 photocatalytic reduction and was compared with the catalytic performance of commercial TiO2 Evonic P25. Logically, the determined physicochemical and optical properties of photocatalysts were correlated with their catalytic performance and some interesting aspects of gold photocatalysis were revealed.
