Mechanochemical Synthesis of Visible Light Sensitive Titanium Dioxide Photocatalyst
Figure 8
Experimental (solid line) and simulated (dotted line) EPR spectra of •DMPO-OH adduct obtained upon irradiation of aqueous TiT 144 ground suspensions in the presence of DMPO ( g l−1, mol l−1): (a) Pyrex (λ > 300 nm), •DMPO-OH concentration of 1.1 μmol l−1 was monitored during 660 seconds of irradiation; (b) GG 435 filter (λ > 435 nm), •DMPO-OH concentration of 0.3 μmol l−1 was measured during 1350 seconds of irradiation.
