Optimization of Anatase TiO₂ Photocatalyst for Diclofenac Degradation by Using Response Surface Methodology

Applied Sciences
Titanium oxide semiconductors are considered effective photocatalysts for the degradation of organic pollutants. The photocatalytic activity of titanium dioxide is influenced by several factors, one of which is its phase composition, with anatase being ...

Zur Rolle von Wasser bei der CO2‐Reduktion an defektreichem TiO2 bei niedrigen Temperaturen

Angewandte Chemie, EarlyView.
Unsere Ergebnisse unterstreichen das Potenzial von reduziertem Titandioxid als edelmetallfreiem Katalysator zur Aktivierung von CO2 und zeigen in situ die Reaktion von CO2 auf defektreichem TiO2 unter Verwendung von synchrotronbasiertem NAP‐XPS von Raumtemperatur bis 700 K.

Vapor-Phase Hydrothermal Transformation of HTiOF3 Intermediates into {001} Faceted Anatase Single-Crystalline Nanosheets

, 2012
For the first time, a facile, one-pot hydrofluoric acid vapor-phase hydrothermal (HF-VPH) method is demonstrated to directly grow single-crystalline anatase TiO2 nanosheets with 98.2% of exposed {001} faceted surfaces on the Ti substrate via a ...

Application of phycocyanin from microalgae Spirulina platensis as light harvesting in anatase TiO2 nanoparticle solar cell.

, 2014
The dye sensitized solar cell (DSSC) has been assemblied used hybrid titanium oxide (TiO2) film/phycocyanin. The TiO2 film was synthesized by sol gel method with titanium chlorida (TiCl4) as precursor by hydrolysis used sulfuric acid (H2SO4). Furthermore,

Role of Water in Low‐Temperature CO2 Reduction at Defect‐Rich TiO2

Angewandte Chemie International Edition, EarlyView.
Our results highlight the potential of reduced titania as a noble metal‐free CO2 activation catalyst and show the activation of CO2 on highly defective TiO2 using in situ synchrotron‐based NAP‐XPS from room temperature to 700 K. The distribution of surface intermediates can be decoded as a simultaneous population of reaction routes, revealing water (OH)

Light-driven high-temperature continuous-flow synthesis of TiO2 nano-anatase

, 2012
Developing continuous-flow high-temperature fabrication strategies constitutes a pivotal challenge in the realization and scale-up of some functional nanomaterials. We have developed a light-driven large-area spinning-disk processor for this purpose, and

Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

Journal of Applied Polymer Science, EarlyView.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

Pseudorutile-leucoxene-quartz ores of Timan ‒ a new genetic type of titanium raw materials: prospects for industrial development

Georesursy
The two largest deposits of Russia – Yaregskoye and Pizhemskoye belong to the same genetic type; hydrothermal-metamorphic indigenous deposits. They are located in the same Timan structure at a distance of no more than 230 km from each other. According to
