Abstract:
This paper is focused on the solution combustion synthesis (SCS) of a set of 90Ni/10Al2O3 (wt. %) catalysts for the production of hydrogen and carbon nanofibers through methane decomposition. A novel approach was employed to optimize the SCS of the catalysts in order to enhance the yields of hydrogen. The obtained catalysts were tested in methane decomposition at 550 °C and 1 bar. Transmission electron microscopy, energy-dispersive X-ray spectroscopy, low temperature nitrogen adsorption, and X-ray diffraction were utilized to investigate the catalysts. The SCS process involved programmable heating of a mixture of Ni(NO3)2·6H2O and Al(NO3)3·9H2O with citric acid (C6H8O7) from room temperature to 350–450 °C at a heating rates 1–10 °C/min and exposure durations of 0–20 min. It was discovered that a high specific yield of hydrogen (17.1 mol/gcat.) and carbon nanofibers (171 g/gcat.) can be achieved by synthesizing at 450 °C using a heating rate of 1 °C/min without additional exposure.
