The effect of impregnation strategy on methane dry reforming activity of Ce promoted Pt/ZrO2

“…Particularly, noble metal catalysts containing ceria as a promoter increase the catalytic reactivity in the oxidation reactions of different hydrocarbons [26][27][28] and enhance the performance characteristics of three-way catalysts used in elimination of pollutants in automobile exhaust [29][30][31]. The unique acid-base and redox properties of ceria influence the dispersion of the active metals on the support as well as oxidation and reduction cycle of noble metals [32,33].…”

Anodized Aluminum Oxide Supported NiO-CeO2 Catalyst for Dry Reforming of Propane

“…This result suggests that some nickel ions (Ni 2+ ) were incorporated into the CeO2 lattice and formed a solid solution of NiO and CeO2 (Ce1−xNixO2−δ) since the size of Ni 2+ ion is smaller than that of Ce 4+ ion [23][24][25][26]. Higher NiO loading inhibited the growth of CeO2 [27][28][29]. The surface morphology of the bare AAO support was examined with field emission scanning electron microscopy (FE-SEM).…”
