One technique that can be used to degrade methylene blue is through a photocatalytic process using ZnO nanoparticles. This study aims to synthesize ZnO nanoparticles using Lidah mertua extract (Sansevieria trifasciata) as a capping agent by the sol-gel method, and determine the characteristics and stability of ZnO nanoparticles in methylene blue photodegradation. The synthesis of ZnO nanoparticles begins with drying Lidah mertua, grinding it, and then extracting it using distilled water. Furthermore, the extract was reacted with Zn(CH3COO)2.2H2O 0.15 M at pH 8. The extract was characterized using Fourier Transform Infrared (FTIR), and the ZnO nanoparticles were characterized using X-Ray Diffraction (XRD), ultraviolet-visible (UV-Vis) DRS, and Scanning Electron Microscopy (SEM). Lidah mertua extract has OH (hydroxyl), CN, CH, and C=C functional groups. The obtained ZnO nanoparticles have a crystal size of 19.324 nm. The crystalline phase is hexagonal; the morphology is spherical, with a particle size of 79.153 nm and a band gap energy of 3.21 eV. ZnO nanoparticles exhibited a methylene blue decolorization of 98.50% through 43.41% by adsorption and 55.09% by photocatalytic mechanism. ZnO nanoparticles showed good stability for a three-cycle reaction. Copyright © 2023 by Authors, Published by BCREC Group.

The purpose of this study is to analyze the magnetic properties of iron sand and review its potential in photocatalytic processes. Before being synthesized, the natural iron sand was separated and milled. The iron sand was dissolved in 37% v/v HCl, stirred, and heated for 30 min. This solution was filtered and precipitated with 6.5 M NH4OH while stirring and heating for 30 min. The magnetite formed was washed repeatedly with distilled water until it reached a normal pH, and then dried. Magnetite characterization tests were performed using XRF, XRD, VSM, and UV-Vis spectroscopy. The test results showed that the iron sand had a high magnetic quality with a concentration of 91.17% after the synthesis process. The resulting magnetite phase structure had a spinal inverse cubic shape, with the highest peak at the Miller index (311). From the VSM test, it is known that the resulting magnetite exists in a soft magnetic form with superparamagnetic groups. From optical absorption, magnetite has a gap energy of approximately 2.8 eV. It can be concluded that the magnetite from Anoi Itam Sabang has potential as a photocatalytic absorbent in the visible light wavelength region. Copyright © 2023 by Authors, Published by BCREC Group.

The electrocatalytic properties within electrochemical cells can be enhanced by modifying the electrode through an electrodeposition process. Therefore, this study aimed to synthesize NiO/Ni electrocatalyst using the electrodeposition method at pH values of 8, 10, and 12. The NiO/Ni generated was applied in the electrochemical degradation of textile waste under specific operating conditions, including pH 4, NaCl concentration of 0.05 M, DC voltage of 9 volts, and varying degradation times of 60, 120, 180, and 240 min. Based on the results, the XRD diffractograms revealed the presence of NiO peaks at 2θ = 43.5°, 63.1°, and 75.4°, and Ni peaks at 2θ = 51.9°. SEM-EDX analysis showed that NiO/Ni was deposited on the graphite surface in the form of spheres and granules. FTIR indicated the presence of Ni−O bonds at 501 cm−1, and GSA demonstrated that NiO/Ni exhibited mesoporous properties. The NiO/Ni at pH 10 had the highest surface area, pore volume, and current response compared to graphite, as well as the electrocatalyst produced at pH 8 and 12. Additionally, the electrochemical degradation of textile waste using NiO/Ni at pH 10 led to the highest reduction in absorbance efficiency, chemical oxygen demand (COD), and ammonia, with respective values of 96.80, 96.15, and 87.34%.

Fe3O4/SiO2/TiO2@Ag composite was employed in the photocatalytic degradation of Congo red dye and antibacterial activity test. The degradation was facilitated by visible light irradiation while considering different factors such as pH solution, the photocatalyst dosage, and the dye's initial concentration. The composite was characterized using X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy-Electron Dispersive X-ray Spectroscopy (SEM-EDS), Vibrating Sample Magnetometer (VSM), and UV-Vis Diffuse Reflectance Spectroscopy (UV-Vis DRS). The findings indicated that the composite exhibited strong magnetic, measuring 49.4 emu/g, with a band gap of 2.92 eV. The composite showed commendable catalytic properties, with degradation efficiency of 96.52% for Congo red dye under conditions: a pH solution of 4, a dosage of 0.5 g/L, and a dye concentration of 10 mg/L at 100 min of irradiation. The photocatalytic degradation kinetic is align with pseudo-first-order reactions. The composite also exhibits remarkable stability and efficiency with 4.83% decline in degradation efficiency after five cycles.

The Box-Behnken Design (BBD) method based on the Response Surface Methodology (RSM) was applied to determine the optimum experimental conditions on the plasma stability and the synthesis gas production. The synergistic effects of input power (P), CO2/CH4 ratio (R), and flow rate (FR) on the CO2, CH4 conversions, H2, CO yields, and the syngas ratio of H2 to CO were studied. With the desirability value of 0.97, the optimum values of 10.05 W (P), 1.03 (R), and 1.58 L.min−1 FR were identified with CO2 conversion of 48.56% and CH4 conversion of 86.67%; H2 and CO yields of 45.87% and 39.43% respectively; and syngas ratio of H2 to CO of 0.88. The study shows that both P and FR have a major significant effect on the reactant conversions and syngas ratio, followed by R. Meanwhile, the value of R has a significant impact on the H2, CO yields followed P and FR. In contrast, the synergistic effects between P-R, P-FR, and R-FR had a weak significant on the CO2 and CH4 conversions, H2 and CO yields, and H2 to CO ratio respectively. The quadratic term coefficients of P, R, and FR had a remarkable effect on all responses. Thus, the synergistic effect of the most important parameters improves the process efficiency.

In this work, Immobilized lipase from Candida Antartica A (CaLA) was utilized as biocatalyst and the effect of using non-pretreated CPO and pre-treated CPO as feedstock were explored. The pre-treatment of CPO involves degumming with acid, washing with water, and bleaching. The enzymatic interesterification was conducted in three-neck flasks using an ultrasonic water bath at 45o C. Few parameter effects on biodiesel production were also investigated, including the effect of molar ratio of CPO to methyl acetate, the effect amount of lipase, and the reusability of immobilized lipase (CaLA) in the interesterification reaction. The highest average Biodiesel yield of 80.6% was obtained from pretreated CPO at a molar ratio of 1:9 with 100 mg (1% w/v) of Immobilized CaLA, after three hours of reaction. Further research on the reusability of immobilized CaLA revealed that the yield of biodiesel reduced significantly after the second run. The results of the present study also demonstrated that Immobilized CaLA performed well at low concentrations but had low stability, with productivity decreasing to 92% upon reuse after the initial run. In order to make Immobilized lipase economically viable, further research must be conducted to overcome its low stability in the reaction.","PeriodicalId":9366,"journal":{"name":"Bulletin of Chemical Reaction Engineering & Catalysis","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90776207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the derivatives of HMF, 5-ethoxymethylfurfural (EMF) is the etherification product of HMF with ethanol. Owing to some advantages (i.e., high energy density), EMF has been regarded as a potential liquid fuel. Therefore, catalytic conversion of HMF and fructose to EMF is of significance, especially using heterogeneous catalysts. In this paper, we demonstrated the preparation of biomass-based catalysts for the synthesis of EMF from HMF and fructose. Some sulfonated biochar catalysts were prepared by the carbonization of biomass-based precursors at high temperature in N2, followed by the subsequent sulfonation process employing concentered H2SO4 as sulfonation reagent. The obtained catalysts were characterized by scanning electron microscope (SEM), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), and element analysis. The catalytic conversion of HMF to EMF was carried out in ethanol, providing a 78% yield with complete conversion at 120 °C. The catalytic activity of the used catalyst showed slight decrease for the etherification of HMF.
