Spectroscopic analyses on ROS generation catalyzed by TiO2, CeO2/TiO2 and Fe2O3/TiO2 under ultrasonic and visible-light irradiation

Catalytically Active CoFe2O4 Nanoflowers for Augmented Sonodynamic and Chemodynamic Combination Therapy with Elicitation of Robust Immune Response

“…Therefore, the bandgap width was calculated from the diffuse reflectance spectrum of CFP (Figure S8). On the basis of the formula E g = 1240/λ g , bandgap energy was calculated to be 1.41 eV, which is tremendously lower than the majority of inorganic sonosensitizers (such TiO 2 , CeO 2 , and BaTiO 3 ). , The rapid energy-motivated separation of electron (e−)/hole (h+) pairs of CFP semiconductors resulting from a narrower bandgap could facilitate enhanced US-mediated ROS production.…”

Heterogeneous photocatalysis: Light-matter interaction and chemical effects in quantum efficiency calculations

“…While nanostructured ceria is an active photocatalyst upon UV and visible light excitation [16][17][18], the contact between ceria and titania is known to provide rather active materials irrespective of the illumination wavelength [19]. Such contact has been applied for the elimination of organic pollutants through reduction and/or oxidation reactions [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] and, very recently, for the inactivation of microorganisms [29,31].…”

Ordered mesoporous C/TiO2 composites as advanced sonocatalysts

“…9-13 For example, Song et al 12 prepared La-doped TiO 2 , which showed a high sonocatalytic degradation rate of amaranth. Zou et al 13 have reported the synthesis of CeO 2 -modied TiO 2 as a sonocatalyst and the reaction rate was 3.3 times as high as that of ultrasound alone. Zhang, and Kubo and their co-workers described that the sonocatalytic degradation rate of organic pollutants in the presence of activated carbon/ TiO 2 composites was 1.2 and 1.5 times higher than that of P25, respectively.…”
