Zeta potential of shape-controlled TiO2 nanoparticles with surfactants

Effect of Ionic Compounds of Different Valences on the Stability of Titanium Oxide Colloids

“…These regimes are separated by the point of zero charge (PZC), which corresponds to the pH, where the overall charge of the particle is zero. The PZC values of numerous titanium oxide particles were determined with various techniques in the past decades [23,31,[53][54][55][56][57][58] and they were found to be in the range of 4-7 [51]. In addition, adsorption of ionic species may also change the charge and the position of the PZC of the titanium oxide materials [19,59].…”

Preparation and characterization of novel Ti0.7W0.3O2–C composite materials for Pt-based anode electrocatalysts with enhanced CO tolerance

“…Moreover, various low temperature sol-gel based methods can be found in the literature for the preparation of pure rutile TiO 2 nanoparticles [16,[31][32][33][34][35]. Recently, an intense effort has also been devoted to loading TiO 2 on activated carbon using sol-gel technique [36][37][38][39].…”

Dye aggregation and influence of pre-micelles on heterogeneous catalysis: A photophysical approach

“…The use of oppositely charged surfactant and dye introduces the advantage of sensitization of TiO 2 from direct interaction of semiconductor and dimers of rhodamine B with the adequate energy transfer from excited dye to titanium dioxide, for instance, allowing the photocatalysis and, consequently, an efficient photodegradation of rhodamine B [15][16][17][18][19], reducing the bandgap from 3.2 eV to intermediate level from which the irradiation in the visible region promotes the excitation of electrons from excited dye to the conduction band of TiO 2 with the electron-hole pair generation.…”
