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
characteristics improvement.},
