      abstract     = {Progress in nanoscale material chemistry in general, and in
                      TiO2 photocatalysis particularly goes on. The past 10 years
                      achievements in the enhancement of photocatalytic activity,
                      hardening of materials, chemical and biological resistance
                      and other unique characteristics contributed to the ability
                      of controlling nanoparticles size and shape, particles
                      organization and their surface chemistry. However, the
                      drawbacks of wide band gap (3,2 eV) and fast electron/hole
                      recombination rate of TiO2, which are limiting TiO2
                      application in sunlight driven photocatalysis and
                      photocatalytic ability in general, still attract the
                      scientists’ attention. In frame of these, there has been
                      great interest for doping and surface modification of TiO2
                      with transition metals as a possibility for photoexcitation
                      in the visible region and charge separation [1]. A lot of
                      work in the field of TiO2 modification with copper and
                      zirconium separately has been done. Both elements showed
                      beneficial results in TiO2 modification [2]. However, double
                      metal modification can lead to additional achievements
                      [3].Copper and zirconium modified photocatalysts were
                      obtained by wet impregnation method of P25 (Evonik Degussa).
                      In order to follow the changes in photocatalytic properties
                      in conjunction with local structure and origin of modified
                      photocatalysts, two types of metal precursors (organic:
                      copper(ll) acetyl acetonitrile, zirconium(lV) isopropoxide,
                      and inorganic: copper nitrate, zirconyl nitrate hydrate)
                      were used. Concentration of metals varied as well.
                      Photocatalytic properties and surface chemistry of obtained
                      materials were investigated. Changes in the quality and
                      quantity of acidic sites on the surface of TiO2 were shown.
                      Durability of photocatalytic films based on obtained powders
                      was checked by pencil hardness test. Obtained results
                      suggest employment of two metals simultaneously for catalyst
