In this paper, photocatalytic TiO2 micro- and nano-powders coated by Ni and Co nanoclusters were prepared by the original electroless deposition method. The magnetic properties of Ni and Co nanoclusters decorating TiO2 grains were studied by the magnetometry measurements of the temperature dependence of magnetization. Their optical spectroscopy measurements showed a significant increase in light absorption by Ni and Co coated TiO2 nanopowders. The photocatalytic properties of the obtained magnetic nanopowders were studied with Electron Paramagnetic Resonance spectroscopy as well.
