We report the synthesis of N-doped TiO(2) nanofibers and high photocatalytic efficiency in generating hydrogen from ethanol-water mixtures under UV-A UV-B irradiation. Titanate synthesized by hydrothermal method are annealed air and/or ammonia to achieve anatase fibers. Depending on route, either interstitial N atoms or new N-Ti bonds appear lattice, resulting slight lattice expansion as shown XPS HR-TEM analysis, respectively. These were then used support for Pd Pt nanoparticles deposited...
Hydrochar derived from Argan nut shell (ANS) was synthesized and applied to remove bisphenol A (BPA) diuron. The results indicated that the hydrochar prepared at 200 °C (HTC@ANS-200) possessed a higher specific surface area (42 m2/g) than (HTC@ANS-180) 180 (17 m2/g). hydrochars exhibited spherical particles, which are rich in functional groups. HTC@ANS-200 high adsorption efficiency, of about 92% BPA removal 95% diuron removal. maximum Langmuir capacities room temperature were 1162.79 mg/for...
Carbon capture and utilization (CCU) is a growing field in chemical engineering with high expectations to replace fossil carbon. This paper focuses on modeling simulation of CCU process chain utilizing biogenic CO2. A scenario pulp mill recovery boiler effluent assumed. CO2 performed membrane-based system. followed by methanol synthesis, the majority produced directed dimethyl carbonate (DMC) synthesis.The fixed design was simulated for different scenarios flue gas properties. The key...
Highly microporous carbons were prepared from argan nut shell (ANS) using steam activation method. The (ANS@H2O-30, ANS@H2O-90, and ANS@H2O-120) characterized X-ray diffraction, scanning electron microscopy, Fourier-transform infrared, nitrogen adsorption, total fluorescence, temperature-programmed desorption (TPD). ANS@H2O-120 was found to have a high surface area of 2853 m2/g. adsorption bisphenol A diuron on investigated. isotherm data fitted Langmuir Freundlich models. model presented...
