Triton X114 was used as the nonionic surfactant and Titanium(IV) isopropoxide and/or Zirconium(IV) propoxide were used as the metal precursors. As treatment method the calcination at temperature 400°C in air was applied. The effect of ZrO2 on photocatalytic properties of prepared mixed-oxide catalyst was evaluated. Textural properties, structural properties, morphol-ogy and purity of prepared catalysts were characterized by nitrogen physisorption at 77K, advanced XRD analysis, TEM, XRF, UV-VIS and organic elemental analysis. For testing of photocatalytic activity the photocatalytic reduction of car-bon dioxide was chosen with methane and methanol as the main reduction prod-ucts.
