“…It is interesting to compare the activation energy of titania sulfonated fish bone-derived carbon with the results of other studies. In general, the activation energy of chemical reactions in the presence of a solid catalyst in liquid-phase oxidation of styrene with hydrogen peroxide is in the range of 20-80 kJ [43]. The results obtained in this research work are in agreement with these results, suggesting that a low-cost fish bone-derived carbon can be used as a catalyst.…”

The kinetic evaluation of titania supported sulfonated fish bone-derived carbon (TiO2/SFBC) as a catalyst in styrene oxidation by aqueous hydrogen peroxide was carried out. The catalysts were prepared by carbonation of fishbone powder at varying temperatures 500, 600 and 700 °C, respectively for 2 h, followed by sulfonation with sulfuric acid (1M) for 24 h and impregnated by varied titania concentration 500, 1000 and 1500 µmol. The physical properties of catalysts were characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) and the nitrogen adsorption-desorption analysis. The catalytic activity result showed that TiO2/SFBC can be used as a potential catalyst in styrene oxidation. Worth noting that the sulfonation process has not only transformed the TiO2/FBC particulates (without sulfonation) to cuboid-shaped TiO2/SFBC (with sulfonation) but also contributed to the high selectivity of benzaldehyde. On the other hand, carbonization at different temperatures has an indistinct effect on catalytic performance due to their similar surface areas. The styrene conversion rate responded positively with the increasing amount of titania in the functionalized composites. The styrene oxidation by aqueous H2O2 unraveled the first-order reaction with the activation energy of ⁓63.5 kJ. Copyright © 2022 by Authors, Published by BCREC Group.

“…Многие из этих химических превращений обернулись в крупнотоннажные промышленные процессы, таящие в себе, тем не менее, значительные резервы модернизации и усовершенствования [2][3][4][5]. В частности, в настоящее время значительный крен в исследованиях делается на использование «зелёных» окислителей [6][7][8][9] а также возможностей нанотехнологии [9][10][11][12].…”

The paper describes the results of aerobic-peroxide catalytic oxidation of naphthalene in the presence of iron-containing multi-walled carbon nanotubes Fe@MWCNT. The active nanocarbon substrate containing α-iron atoms and carbides realizes by the Fenton reaction active formation of active particles and intensive oxidation of the hydrocarbon under rather mild conditions. It was found that at the temperature range 333 - 353K, in the presence of hydrogen peroxide (30% aqueous solution) and Fe@MWCNT (Fe ≈3.7 wt. %), under intense air current, the reaction proceeds without destroying the cyclic structure of the molecule with predominant formation of phthalic anhydride and naphthol. Identification of the functional groups of the main target products was performed by the infrared (IR) spectroscopy. The results obtained can be proposed for further development of such studies and bringing them into compliance with the standards of the industrial process. Keywords: aerobic oxidation of hydrocarbons; oxidation of naphthalene; hydrogen peroxide; multi-walled carbon nanotubes; nanocarbon catalysis; Fenton system, oxygencontaining aromatic compounds.
