Abstract

The utilization of fishbone as the carbon source for methylene blue adsorption has been successfully studied. Fishbone was prepared from two kinds of fish such as marine fisheries (ex. Tenggiri) and freshwater fisheries (ex. Belida). The carbons were prepared by carbonation of fishbone powder at  500 °C for 2 h. Physical properties of carbons were characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), wavelength dispersive X-ray fluorescence (WDXRF), Scanning Electron Microscope (SEM), and hydrophobicity. The carbons were utilized as the adsorbent for removing methylene blue by varying the contact time, initial dye concentration, and temperature. It is concluded that both carbons can very good adsorb the methylene blue. The adsorption performance of carbon (TFC) from Tenggiri fish is better than carbon (BFC) from Belida fish. The adsorption was well fitted with the Langmuir adsorption model (R2 ~ 0.998) and the pseudo-second-order model. This indicated that the dye molecules were adsorbed on the surface-active site of carbon via chemical binding, forming an adsorbate monolayer. Thermodynamic parameters, including the Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS), indicated that the adsorption of methylene blue onto the carbon from fishbone was spontaneous. Thus, carbon from fishbone can be applied as a low-cost adsorbent to treat industrial effluents contaminated with methylene blue. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

This paper presents the synthesis and characterization of calcium sulfate hemihydrate (CSH)-supported titania (TiO2) catalysts and their application in the environmentally friendly oxidation of styrene to benzaldehyde using hydrogen peroxide (H2O2) as the oxidant. The study explores the catalyst's structure-activity relationship, emphasizing the importance of mesoporous materials for enhanced catalytic performance. The CSH-Titania catalysts were synthesized using fish bone-derived CSH as a support, which aligns with green chemistry principles. Characterization techniques such as Fourier Transform Infra Red (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Brunauer-Emmett-Teller (BET) surface area analysis confirmed the successful impregnation of titania and its catalytic efficiency. The catalysts exhibited high selectivity for benzaldehyde, achieving up to 49.45% conversion of styrene, with benzaldehyde as being the main product. The research highlights that the catalyst’s performance decreased after calcination due to a reduced surface area and pore volume, yet it maintained recyclability across three cycles with minimal  lose  in selectivity loss. Overall, this study introduces a cost-effective and sustainable approach to styrene oxidation, demonstrating the potential for industrial application in producing high-value chemicals with minimal environmental impact.

Abstract

Wastewater pollution is mainly produced from the dye textile industry and the most widely used photocatalyst to degrade dye textile is TiO2 due to its photostability, low toxicity, and low production cost. However, TiO2 is only responsive under UV light; thus, our study is to extend the TiO2 absorption light to visible region via doping of bio-based carbon source, viz. ascorbic acid, to produce carbon-doped TiO2. The carbon-doped TiO2 were solvothermally synthesized with varying carbon loadings (10, 30, and 50 wt%) and calcination temperatures (250, 300, and 400 oC). The functional groups of carbon-doped TiO2 were determined, which the carbonyl groups (C=O) at 1700 cm-1, alkenyl groups (C=C) at 1630-1670 cm-1, hydroxyl groups at 3380-3390 cm-1, and TiO2 appeared at 450 cm-1. The absorption spectra shifted from UV to visible-light region and the band gap was reduced compared to undoped TiO2. The photoluminescence results showed that the surface oxygen vacancies (SOVs) are generated for carbon-doped TiO2. The Ti–C bond formation was proved through diffractogram peak shifting, while the crystallite sizes decrease with increasing carbon amount and decreasing calcination temperature. The highest methylene blue photodegradation of 89.53% was achieved by 30 wt%C-TiO2-250 photocatalyst at pH 10 under 2 h visible light irradiation.
