Rh, Ni, and Ca substituted pyrochlore catalysts for dry reforming of methane

Journal Article Gaur, Sarthak ; Haynes, Daniel J. ; Spivey, James J. - Appl. Catal. A-Gen

Dry reforming of methane (DRM) has been widely investigated, with most studies showing rapid deactivation due to carbon deposition. This suggests a need to develop catalysts that limit carbon formation while avoiding structural changes at the elevated temperatures typical of this reaction. Here, we report CO₂ reforming of methane on four pyrochlore catalysts. First, rhodium was partially substituted for Zr in lanthanum zirconate (La₂Zr₂O₇) to give La₂Zr _2−xRh _xO _7−δ (LRZ, x = 0.112, 2 wt% Rh) pyrochlore. A second pyrochlore catalyst was synthesized in which Ca was further substituted into the La-site to give La _1.95Ca _0.05Zr _2−xRhmore »« less

Double Perovskite Anode Materials Sr2MMoO6 (M = Co, Ni) for Solid-Oxide Fuel Cells

Journal Article Huang, Y. ; Liang, G ; Croft, M ; ... - Chemistry of Materials

Double-perovskites Sr2MMoO6 (M = Co, Ni) have been investigated as anode materials for a solid oxide fuel cell. At room temperature, both Sr2CoMoO6 and Sr2NiMoO6 are tetragonal (I4/m). X-ray absorption spectroscopy confirmed the presence of Co2+/Mo6+ and Ni2+/Mo6+ pairs in the oxygen-stoichiometric compounds. The samples contain a limited concentration of oxygen vacancies in the reducing atmospheres at an anode. Reoxidation is facile below 600 C; they become antiferromagnetic at low temperatures TN = 37 and 80 K for M = Co and Ni, respectively. As an anode with a 300 em thick La0.8Sr0.2Ga0.83Mg0.17O2.815 electrolyte and SrFe0.2Co0.8O3-d as a cathode, Sr2CoMoO6more »« less

Effect of Nickel Microstructure on Methane Steam-Reforming Activity of Ni-YSZ Cermet Anode Catalyst

Journal Article King, David L. ; Strohm, James J. ; Wang, Xianqin ; ... - Journal of Catalysis, 258(2):356-365

The activity of nickel-yttria stabilized zirconia (Ni-YSZ) solid oxide fuel cell (SOFC) cermet anodes for the steam reforming of methane has been investigated in the absence of electrochemical effects. The cermet was prepared by co-milling and sintering NiO and 5YSZ powders at 1375oC in air. During the high temperature sintering step, NiO dissolved into the YSZ particles to form a solid NiO-YSZ solution. During the subsequent catalyst reduction step, Ni exolved from the YSZ. As a result, many small Ni particles on the order of 10-20 nm formed at the surface of the YSZ. These small particles contribute significantly tomore »« less

Electronic and protonic conduction in LaFeO ₃

Journal Article Zhu, Zhen ; Peelaers, Hartwin ; Van de Walle, Chris G. - J. Mater. Chem. A

Perovskite-type LaFeO3 has promising applications as a negative-electrode material for Ni/metal-hydride batteries. To further improve electrode performance, a thorough understanding of its charge-transport mechanisms is required. We use hybrid density functional theory to investigate the structural and electronic properties of bulk LaFeO3, as well as the effect of point defects and polarons on charge transport. Electronic charge localizes in the form of small hole and electron polarons; this self-trapping occurs in the bulk and also in the vicinity of point defects and impurities. We find that oxygen vacancies act as deep donors, while Fe and La vacancies are acceptors withmore »« less

Role of support in CO{sub 2} reforming of CH{sub 4} to syngas over Ni catalysts

Journal Article Ruckenstein, E. ; Hu, Yun Hang - Journal of Catalysis

The dynamic changes in activity and selectivity for the CO{sub 2} reforming of CH{sub 4} over unsupported and supported Ni catalysts were investigated. The reduced NiO has low initial conversions of CH{sub 4} and CO{sub 2}, which decrease rapidly with time. The mixture of powders of NiO and Al{sub 2}O{sub 3} has low initial conversions of CH{sub 4} and CO{sub 2} and a low yield to CO, which however, increase with reaction time, due most likely to Ni migration to Al{sub 2}O{sub 3}. In contrast, the reduced 1 wt% Ni/Al{sub 2}O{sub 3} catalyst (reduced from NiO/Al{sub 2}O{sub 3}) has highmore »« less
