2. Synthesis of TiO2/ZnO photoanodes on FTO conductive glass for photovoltaic applications
Abstract For oxide semiconductors for application in dye-sensitized solar cells (DSSCs), titanium dioxide conjugated with zinc oxide thin films was synthesized and characterized. The UV (ultraviolet) spectrum characterization showed a peak of absorbance at around 355 nm, with a band gap of 3.25 eV and reflectance around 85%. Such characteristics allowed the

3. Enhancement of Visible Light-Responsive Photocatalytic Efficiency by Using a Laccaic Acid-Modified Titanium Dioxide Photocatalyst
In this study, a laccaic acid-modified TiO2 photocatalyst (Lac-TiO2) was prepared via an impregnation method with 0.50, 1.00, 2.50, and 5.00 wt.% laccaic acid. The products’ physical properties were examined through X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), X-ray photoemission spectroscopy (XPS), UV-Vis diffused

5. Challenges of TiO2-composite, as a visible active photocatalyst material for SARS-CoV-2 antiviral compared with the other viruses
The efforts in dealing with COVID-19 in various aspects are continuously being carried out, such as the photocatalytic process. Interestingly, TiO2 plays an important role as an environmentally friendly photocatalyst with a visible and UV absorption range. The increase in the antiviral performance of this compound is further maximized by formulating TiO2-bas

7. Biphasic 0.8BaTiO3/0.2Ni(1-x)CoxFe2O4 nanopowders by in situ sol-gel synthesis
Abstract Nanopowders of the 0.8BaTiO3/0.2Ni(1-x)CoxFe2O4 (x=0, 0.25, 0.5, 0.75, and 1) were synthesized by the in situ sol-gel method using poly(acrylic acid) (PAA1800) as a chelating agent. The synthesis developed using PAA1800 ensured the simultaneous crystallization of two phases. The results provided a reliable method for producing biphasic nanopowders i

9. Zinc tungstate: a review on its application as heterogeneous photocatalyst
Abstract ZnWO4 crystallizes in a monoclinic wolframite-like structure, which has been studied for applications in heterogeneous photocatalysis for degradation, oxidation, and reduction of various contaminants. This type of tungstate has proved to be an efficient photocatalyst under both ultraviolet and visible light irradiation and, when ZnWO4 forms a hetero

12. Cadmium accumulation and toxicity in watercress (Barbarea verna), chicory (Cichorium endivia) and rocket (Eruca sativa) plants
ABSTRACT Some vegetables have the ability to accumulate cadmium (Cd)at levels that are toxic to most other plants. The objective of thisstudy was to evaluate the Cd accumulation and its toxic effects on edible vegetables. Three species were tested: watercress (Barbarea verna); chicory (Cichorium endivia); rocket (Eruca sativa) and four Cd doses (0; 1.5; 3.0;
