Fully bio- and CO2-sourced non-isocyanate polyurethanes (NIPUs) were synthesized by reaction of carbonated soybean oil (CSBO) either with biobased short diamines or amino-telechelic oligoamides derived from fatty acids to achieve respectively thermoset thermoplastic NIPUs. Biobased vegetable oils first obtained metal-free coupling reactions CO2 epoxidized under supercritical conditions (120 °C, 100 bar) before complete characterization FTIR, 1H NMR, electrospray ionization mass spectroscopy...
Photocatalytic degradation of phenol and benzoic acid in aqueous solution was studied using zinc oxide (ZnO) powder synthesized by sol–gel process. Synthesized catalyst characterized X-ray diffraction transmission electron microscopy. The Brunauer–Emmett–Teller surface area, pHpzc, the band gap samples were also measured. influence various key parameters such as amount photocatalyst, initial pH, concentration investigated.
Abstract In this study we report, the synthesis of ZnO and its doping with Transition Metal Oxides -TMO-, such as Cr 2 O 3 , MnO FeO, CoO, NiO, Cu CuO. Various characterization techniques were employed to investigate structural properties. The X-ray diffraction (XRD) data Rietveld refinement confirmed presence TMO phases that structure was not affected by which corroborated using transmission Electron microscopy (TEM). Surface areas low due blockage adsorption sites particle aggregation....
Highly efficient and chemoselective singlet oxygen oxidation of unprotected methionine was performed in water using a continuous mesofluidic reactor. Sustainable process engineering conditions were combined to maximize efficiency atom economy, with virtually no waste generation safe operating conditions. Three water-soluble metal-free photosensitizers [Rose Bengal, Methylene Blue, tetrakis(4-carboxyphenyl)porphyrin] assessed. The best results obtained Rose Bengal (0.1 mol %) at room...
In this paper, TiO₂ prepared with an aqueous sol-gel synthesis by peptization process is doped nitrogen precursor to extend its activity towards the visible region. Three N-precursors are used: urea, ethylenediamine and triethylamine. Different molar N/Ti ratios tested adapted for each dopant. For urea- trimethylamine-doped samples, anatase-brookite nanoparticles of 6-8 nm formed, a specific surface area between 200 275 m²·g-1. ethylenediamine-doped formation rutile phase observed, 185 240...
Abstract Hydrodechlorination of 1,2‐dichloroethane on Pd‐Ag alloys was used as a test reaction in order to study mass transfer carbon xerogel supports. The selected supports were obtained from evaporative drying and pyrolysis resorcinol‐formaldehyde aqueous gels. Since the pore texture these materials can be tailored through adequate choice gel synthesis conditions, maximum size fixed at 10 × −9 m, 30 m (mesoporous supports), or 70 (macroporous support). One Pd‐Ag/activated catalyst also...
