Kinetic Study of Styrene Oxidation over Titania Catalyst Supported on Sulfonated Fish Bone-derived Carbon

Abstract

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.

Synergistic Ti-Fe Oxides on Fishbone-Derived Carbon Sulfonate: Enhanced Styrene Oxidation Catalysis

“…This is one of the reactions that can be employed as it is interesting from both industrial and scientific perspectives. Examples of monometallic transition metals introduced onto material support in styrene oxidation reactions include MCM-48 [9], Cu [10], Pd [11], La [6], Ti [7,[12][13][14], Mn [15][16], Fe [13], V [17], and Cr [18]. However, styrene conversion and benzaldehyde selectivity remain low when monometallic transition metals are used on diverse material supports as catalysts.…”

Comparative Adsorption Performance of Carbon-containing Hydroxyapatite Derived Tenggiri (Scomberomorini) and Belida (Chitala) Fish Bone for Methylene Blue

“…Tenggiri (Scomberomorini)) and aquaculture (ex. Belida (Chitala)) with a sustainable production potential of around 67 million tons/year [14,15]. The consequence of abundant fish yields is that large amounts of fish bone waste have been produced.…”

“…The compositions of fish bone waste are composed of calcium phosphate, collagen fiber, calcium carbonate, and hydroxyapatite [16,17], which are very useful for several applications, namely photocatalysts [18,19], catalysts [20,21], adsorbents [22][23][24], etc. Captivated by the high carbon-containing hydroxyapatite of the fish bone, our research team has explored the usage of modified fish bone as a catalyst in styrene oxidation [15,25] and an adsorbent in methylene blue removal [26,27].…”
