“…At long deposition time, one could see apparently a strong resonance line corresponding to the room temperature superparamagnetic state formed by Co clusters and oxygen vacancies [9]. It was found that the optimal time for Co-deposition is 20 s. It is also confirmed by the analysis of the optical absorption spectra and EPR spectra [8].…”

“…So, TiO 2 (P25) nanopowders with Ni nanocluster coatings should be more suitable for photocatalysis, not only because of the larger specific surface area, but also due to the higher specific efficiency of the surface. EPR study of the photocatalytic activity of TiO 2 /Ni nanopowders was also carried out [8].…”

“…Figure 7 shows the results of the corresponding investigations: curve 1 corresponds to the absorption spectrum of ZnO thin film containing 3% of nickel impurities before decorating its surface with silver clusters and curve 2 does the same after decorating its surface. There is an obvious increase in the light absorption after the clusters are applied to the surface, but the effect is much smaller than in the case of decorating nanopowders [17]. We suggest that the reason is that the surface area is much larger in the case of nanopowders than in the case of thin films.…”

“…In efforts to find inexpensive materials with sufficiently high activity to evolve H 2 , oxides of first-row transition metals appear promising. Oxides of Cr, 10 Mn, 11,12 Fe, 12 Co, 12,13 Ni, 12,14,15 and Cu 14,[16][17][18][19] have been shown to appreciably enhance the H 2 (or O 2 ) evolution activity of the host material. Among those compounds, nickel oxide is especially suitable for photocatalytic H 2 evolution.…”
