The radical intermediates formed upon UVA irradiation of titanium dioxide suspensions in aqueous and non-aqueous environments were investigated applying the EPR spin trapping technique. results showed that generation reactive species their consecutive reactions are influenced by solvent properties (e.g., polarity, solubility molecular oxygen, rate constant for reaction hydroxyl radicals with solvent). formation radicals, evidenced as corresponding spin-adducts, dominated irradiated TiO2...
Bismuth vanadate has attractive photocatalytic properties under visible light. The influence of structure and morphology BiVO4 nanomaterials on its in the UV domain was investigated. selection different sets synthetic parameters aqueous solution—pH or use organic additives—allowed formation tetragonal zircon, scheelite, monoclinic scheelite morphologies that last phase. First, zircon found to be only inactive structure. Then, best material for degradation rhodamine B solution stearic acid...
Approaching living systems, aqueous solutions are appropriate to characterize antioxidants, whereas the frequently used standard 1,1-diphenyl-2-picrylhydrazyl (DPPH) is insoluble in water. Therefore, mixed water–ethanol solvents were investigated using electron paramagnetic resonance (EPR) spectroscopy. Two forms of DPPH identified: at higher ethanol ratios a quintet spectrum characteristic solutions, and lower ratios, singlet typical for solid DPPH, found. Mixed with 0–50% (v/v) water...
We report for the first time synthesis and use of a visible light-sensitive anthraquinone functional phthalocyanine (AQ-ZnPc) in combination with suitable electron donor (methyldiethanol amine, MDEA), acceptor (iodonium salt), or H-donor (thiol derivative, trithiol) as photoinitiating systems free-radical cationic photopolymerization. These unprecedented combinations FRP CP under light irradiation promoted high acrylate epoxy conversions efficiency comparable to well-known...
This study reports for the first time use of β-carotene as a natural photosensitizer both cationic photopolymerization and thiol-ene click reactions under visible-light irradiation. In an all-green synthesis approach, this performing dye-based system leads to polymerization bio-based monomers, mono- di-epoxy limonene, with very high final conversions, appears efficient common photosensitizers used in free-radical or photopolymerization, that is, thioxanthone derivatives camphorquinone....
