Abstract

Uniform nanosheet and nanoflower NiMoO4 structures have successfully been grown on γ-Al2O3 catalyst support using solvothermal method. The NiMoO4 structure could be controlled by varying the catalyst preparation temperature and precursor concentration. The conversion of propane and carbon dioxide into synthesis gas (CO+H2) was performed in an atmospheric-pressure plasma reactor packed with the NiMoO4/γ-Al2O3 catalysts at different temperature. The plasma substantially enhanced the propane and carbon dioxide conversion and increased the hydrogen yield. The nano-structured catalysts exhibited good catalytic activity and selectivity for the strongly endothermic dry reforming, and were chemically stable, resulting in enhanced resistance to coke formation and sintering. Notably, the catalytic activity of the NiMoO4/γ-Al2O3 led to stoichiometric reaction and negligible byproducts. The post-characterization of the used catalysts were characterized using scanning electron microscopy, temperature programmed oxidation, and Raman spectroscopy, which confirmed the less carbon formation and no structural deformation after the reforming reactions.
