Abstract:
This study presents the synthesis and characterization of Ni/Al₂O₃ catalysts prepared via one-pot solution combustion synthesis (SCS) using tartaric acid as a fuel. This is the first time tartaric acid has been used as a fuel to produce a nickel-based catalyst for the decomposition of methane (and C₂–C₄ associated petroleum gas (APG)). The research aimed to identify optimal synthesis parameters to maximize catalytic activity in the decomposition of methane and associated petroleum gas for the coproduction of hydrogen and carbon nanofibers. An experimental design approach was employed to efficiently test the catalysts. Characterization techniques included scanning and transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and low-temperature nitrogen adsorption. The results demonstrated that catalysts prepared with a fuel-to-oxidizer ratio (φ) of 0.183, combined with a low synthesis temperature and heating rate (350°C, 1°C/min), exhibit exceptional activity, achieving a carbon yield of up to 49.3 g/gcat.. These catalysts feature specific surface areas ranging from 60 to 176 m²/g, indicating a highly active and promising material for the efficient decomposition of methane toward turquoise hydrogen and CNFs. A comparison of the decomposition of methane and the mixture simulated associated petroleum gas was carried out, showing more than a twofold increase in the rate of carbon formation, reaching 12.6 g/(gcat.·h) for APG and 4.57 g/(gcat.·h) for CH4. It was found that the formation of active carbon during the decomposition of APG led to faster deactivation of the catalyst but allowed carbon yields at the level of 60–75 g/gcat. to be achieved in only 6 h (550°C, 1 atm).
