Hierarchical NiMoO₄ structures assembled from well-aligned uniform nanosheets(NS) or nanoflowers(NF) have successfully grown on γ -Al₂O₃ substrates utilizing an active catalyst for dry reforming. The structure of the NiMoO₄ can control by using different temperature. This catalyst is active, selective and stable for the strongly endothermic dry reforming of propane (DRP), as the consequence of its enhanced resistance to coke and sintering. Notably, the catalytic activity of NiMoO₄/γ-Al₂O₃ shows that the stoichiometric reaction and negligible by-product. The post characterization of the catalyst of FE-SEM, temperature programmed oxidation (TPO) and Raman result confirmed the less carbon formation and no structural deformation after DRP.
