Abstract

A subclass of Metal-Organic Frameworks, Zeolitic Imidazole Frameworks-8 (ZIF-8) is known as an emerging material that has the characteristic of a large surface area, good thermal stability as well as a high porosity. Instead of having extraordinary properties, ZIF-8 consists of Lewis acid and Lewis base site on its Zn metals and 2-methylimidazole which are the important components for the catalyst. In this study, Pd-Poly(N-vinyl-2-pyrrolidone) coated on ZIF-8 (Pd-PVP@ZIF-8) was synthesized by mixed Pd-PVP solution and ZIF-8 precursors at room temperature. The Pd-PVP solution was varied from 10 to 50 ml to differentiate the Pd concentration in ZIF-8. As-synthesized 50 ml of Pd-PVP on ZIF-8 (50Pd-PVP@ZIF-8) showed catalytic activity in the conversion of 98.6% lauric acid to produce 78.2% of 1-dodecanol at optimum condition 320 °C for 6 h. The synergy between Pd-PVP as metal and ZIF-8 as metal support as well as high dispersion of Pd particles could enhance performance in the conversion of lauric acid.

Abstract

Ethylene glycol, a crucial compound extensively utilized in solvents, coolants, antifreeze, polyester fiber production, and as a natural gas-drying agent, can be synthesized via the hydrogenation of ethylene carbonate. In this study, the synthesis, characterization, and catalytic performance of Cu-Ni/SiO2 catalysts for this reaction, utilizing silica (SiO2) derived from rice husk ash, were investigated. Silica was impregnated with copper (Cu) and nickel (Ni) by varying the weight ratio (Cu:Ni = 10, 7:3, 3:7, 10) to prepare bimetallic catalysts. X-ray Diffraction (XRD) analysis confirmed the presence of both Cu and Ni phases in all the catalysts. The 3Cu7Ni/SiO2 catalyst displayed the lowest reduction temperature and the largest surface area (257.97 m²/g). The 7Cu3Ni/SiO2 catalyst exhibited the highest acidity (1.91 mmol/g) and superior metal dispersion, as confirmed by the Field Emission Scanning Electron Microscopy - Energy Dispersive X-Ray (FE-SEM-EDX) analysis. Catalytic activity was evaluated in a batch reactor under 40 bar H2 pressure at 150 °C for 3 h with a catalyst-to-ethylene carbonate ratio of 5:1. Among the catalysts examined, the 7Cu-3Ni/SiO2 composition demonstrated the highest catalytic performance, achieving 15.14% conversion of ethylene carbonate and 80.51% selectivity towards ethylene glycol.

Abstract

Bentonite can be used as a catalyst due to its flexible structure. However, it has several drawbacks, including low thermal and hydrothermal stability, as well as a small surface area and pore volume. This study aims to modify the structure of bentonite using the pillared clay (PILC) method, in order to improve its physicochemical properties and catalytic activity. The bentonite was pillared with aluminium (Al/PILC), nickel (Ni/PILC), and a combination of both metals (Al-Ni/PILC). Catalyst characterization was carried out using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Surface Area Analyzer (SAA), Fourier Transform Infrared Spectroscopy (FTIR), Temperature Programmed Desorption of Ammonia (TPD-NH₃), Thermogravimetric Analysis-Differential Scanning Calorimetry (TGA-DSC), and Gas Chromatography with Flame Ionization Detection (GC-FID). XRD analysis showed an increase in the interlayer spacing, the largest basal spacing is observed in Al/PILC. XRF results indicated an increase in the composition of Al₂O₃ and NiO in all four catalysts. SAA analysis demonstrated an increase in surface area and pore volume across the catalysts, the highest surface area is exhibited by Al/PILC (187.83 m2/g), while the largest pore diameter is observed in Al-Ni/PILC (12.83 nm). The acidity analysis using TPD-NH₃ shows that Al/PILC possesses the highest acidity value of 2.34 mmol/g. The presence of Brønsted acid sites was confirmed through FTIR analysis. TGA-DSC analysis indicated an improvement in the thermal stability of all tested catalysts. The Al/PILC catalyst showed the best performance at 150 °C. When the reaction temperature was increased to 250 °C, the Al-Ni/PILC catalyst demonstrated the highest efficiency in the ethanol-to-gasoline conversion process.
