Photocatalytic decomposition of diclofenac potassium using silver-modified TiO2 thin films

Atomic scale characterization and surface chemistry of metal modified titanate nanotubes and nanowires

“…The presence of silver reduces the specific surface area and increases the degree of crystallinity of the titanate nanoparticles. A possible explanation concerning the role of Ag þ in enhancing the crystallinity of the sample could be related to its activity in suppressing the formation of Ti 3 þ species [366]. Rh-induced support transformation phenomena in titanate nanowires and nanotubes were studied with Raman spectroscopy, XRD and HRTEM in detail [183].…”

Synthesis and characterization of B-doped TiO2 and their performance for the degradation of metoprolol

“…The sol-gel method was used to synthesize the TiO 2 and Bdoped TiO 2 [45,46]. The procedure consists in mixing titanium(IV) isopropoxide with glacial acetic acid (molar ratio 1:4) under constant stirring to form the complex.…”

Aqueous degradation of diclofenac by heterogeneous photocatalysis using nanostructured materials

“…Some photoproducts were identified and related to the photodegradation mechanism [21][22][23]. Cavalheiro et al found an enhancement of DIC's photodegradation rate, as well as an increase in the number of by-products, when silver-modified TiO 2 thin films were used as catalysts instead of TiO 2 [24]. Bartels et al followed the decrease of aqueous DIC concentration and the appearance of phototransformation products under natural irradiation during a period of one to sixteen days [25].…”
