Ceria doping boosts methylene blue photodegradation in titania nanostructures

Abstract

Ceria-doped titania photocatalysts (ceria loading 0.25-5.0 wt.%) were synthesized by hydrothermal methods for water remediation. Nanotubes (CeTNTx) and nanoparticles (CeTNPx) were obtained. Ceria doping was applied to tune the electronic...

Surface Defect Engineering in Colored TiO2 Hollow Spheres Toward Efficient Photocatalysis

“…Hence, their release from wastewater industries is extremely dangerous both for the environment and human health. [6][7][8] Ciprofloxacin (CIP) is a broadspectrum second-generation fluoroquinolone antibiotic and one of the most widely used and prescribed. Additionally, it has been proved that CIP is not only present in different water effluents all over the world, but it is also exceeding the safe concentration limit for antimicrobial resistance in several sites.…”

Titania/chitosan–lignin nanocomposite as an efficient photocatalyst for the selective oxidation of benzyl alcohol under UV and visible light

“…Nanostructured-titania is one of the most widely studied photocatalysts, due to its low cost, high photocatalytic activity and stability. 27 Despite of several advantages, there are few drawbacks of titania which limits its application in certain fields of photocatalysis, especially in organic synthesis. For example, titania exhibits high recombination rate of electron–hole pairs and lacks an appropriate band-gap 28 required for the visible light absorption ( i.e.…”

Preparation, Characterization of Green Synthesis CeO2 Nanoparticles and Their Photocatalytic Activity towards Malachite Green Dye

“…All of these factors contribute to the value of our findings when compared to other publications. [26,[56][57][58][59][60][61] To detect the reaction mechanism the tertiary-butanol (t-BuOH), 1,4-benzoquinone (BQ), and ammonium oxalate (AO) scavengers were added to explore the role of hydroxyl radicals ( * OH), superoxide radicals (O 2 *À ), and hole (h + ) in the degradation of MG dye. [11,62] Decreasing the photodegradation during the scavenger added, indicating that the radical is in control dye degradation.…”
