Room temperature synthesis of protonated layered titanate sheets using peroxo titanium carbonate complex solution.

چکیده
We report the synthesis of peroxo titanium carbonate complex solution as a novel water-soluble precursor for the direct synthesis of layered protonated titanate at room temperature. The synthesized titanates showed excellent removal capacity for Pb(2+) and methylene blue. Based on experimental observations, a probable mechanism for the formation of protonated layered dititanate sheets is also discussed.

Modafinil (Diphenyl methyl Sulfinyl acetamid) is used clinically in the treatment of narcolepsy and sleeping disorders. The synthesis of R-modafinil, have started with the reaction of benzhydrol and thioglycolic acid in trifluoroacetic acid to afford benzhydryl sulfanyl acetic acid. The reaction of acid with thionyl chloride in benzene followed by treatment with ammonium hydroxide gave acetamid...
متن کاملSynthesis and application of layered titanates in the photocatalytic degradation of phenol
This study proposes a direct synthetic route to single titanate sheets through the mild and versatile conditions of the “chimie douce”. The stages of the production include the complexation of the titanium alkoxide precursor by benzoic acid, the formation of titanium oxo-clusters and their controlled transformation into single sheet titanates during the hydrolysis stage. The resulted material a...
متن کاملSynthesis of High Surface Area Titania Based Nanoparticles and the Effect of Surfactants
In this study, TiO2 based nanotubes and nanosheets were synthesized to be used as an adsorbent and support in various processes. As a starting material, sol-gel synthesized anatase and commercial anatase were used. TiO2 was converted to high surface area hydrogen titanate (H2Ti3O7) and sodium titanate (Na2Ti3O7) nanotubes and nanosheets under alkaline conditions with hydrothermal treatment. In ...
