Abstract

The catalytic yields of partial oxidation of methane (POM) to hydrogen over M(1)-Ni(5)/Al₂O₃(M=, Ce, La, Y) catalysts were investigated using a fixed bed flow reactor under atmospheric pressure to solve the global warming problem and clean energy demand. Catalyst activity is evaluated by performing the reaction of POM to hydrogen, and active sites of the catalyst are verified by instrumental analysis. The catalysts were characterized by XPS, XRD, FESEM, EDS, FETEM. The crystal phase behavior of reduced La(1)-Ni(5)/AlCeO₃ catalysts before and after the reaction were studied by XRD analysis. The crystalline phase of Ni and La on La(1)-Ni(5)/AlCeO₃ reduced before reaction was not obserbed due to uniform distribution of nanoparticles. FESEM and EDS analyses show that nanoparticles of Ni, La and Ce are uniformly distributed on the catalyst surface. In addition, TEM images and EDS mapping of La, Ni, Ce, O, and Al for a reduced La(1)-Ni(5)/AlCeO₃ catalyst before reaction show that the elements are well distributed. When 1 wt% of La was added to Ni(5)/AlCeO₃ catalyst, XPS results showed that O^-, O_vacancy, and O₂^- species, Ni₂p_3/2, and Ce3d_5/2increased 1.4, 52.7, 6.3% on the La(1)- Ni(5)/ AlCeO₃ catalyst, respectively. The yield of hydrogen on the La(1)- Ni(5)/ AlCeO₃ catalyst was 89.1%, which was much better than that of M(1)-Ni(5)/Al₂O₃(M=Ce, Y) catalysts. As Ce⁴⁺/Ce³⁺ ions in CeO₂ produced by the reaction of AlCeO₃ with oxygen were substitute to La³⁺, Ni²⁺, it made oxygen vacancies in the lattice and further improved the hydrogen yield by increasing the dispersion of Ni atoms with strong metal- support interaction (SMSI) effect.

AB  - The catalytic yields of partial oxidation of methane (POM) to hydrogen over M(1)-Ni(5)/Al2O3(M=, Ce, La, Y) catalysts were investigated using a fixed bed flow reactor under atmospheric pressure to solve the global warming problem and clean energy demand. Catalyst activity is evaluated by performing the reaction of POM to hydrogen, and active sites of the catalyst are verified by instrumental analysis. The catalysts were characterized by XPS, XRD, FESEM, EDS, FETEM. The crystal phase behavior of reduced La(1)-Ni(5)/AlCeO3 catalysts before and after the reaction were studied by XRD analysis. The crystalline phase of Ni and La on La(1)-Ni(5)/AlCeO3 reduced before reaction was not obserbed due to uniform distribution of nanoparticles. FESEM and EDS analyses show that nanoparticles of Ni, La and Ce are uniformly distributed on the catalyst surface. In addition, TEM images and EDS mapping of La, Ni, Ce, O, and Al for a reduced La(1)-Ni(5)/AlCeO3 catalyst before reaction show that the elements are well distributed. When 1 wt% of La was added to Ni(5)/AlCeO3 catalyst, XPS results showed that O-, Ovacancy, and O2- species, Ni2p3/2, and Ce3d5/2 increased 1.4, 52.7, 6.3% on the La(1)- Ni(5)/ AlCeO3 catalyst, respectively. The yield of hydrogen on the La(1)- Ni(5)/ AlCeO3 catalyst was 89.1%, which was much better than that of M(1)-Ni(5)/Al2O3(M=Ce, Y) catalysts. As Ce4+/Ce3+ ions in CeO2 produced by the reaction of AlCeO3 with oxygen were substitute to La3+, Ni2+, it made oxygen vacancies in the lattice and further improved the hydrogen yield by increasing the dispersion of Ni atoms with strong metal- support interaction (SMSI) effect.
