- W4293289214 abstract "Deposition of La2O3 and Al2O3 on Al2O3-supported Ni catalysts was performed to study their effects on heterogeneous catalysts for the dry reforming of methane (DRM) reaction. An alumina-supported Ni catalyst (Ni/Al2O3, 2 wt % of Ni), synthesized via incipient wetness impregnation, loses ∼87% of its initial activity within 45 h under DRM conditions. While overcoating of Al2O3 on this catalyst via atomic layer deposition (ALD) helps stabilize the catalytic activity in long time-on-stream (TOS) tests, this overcoated catalyst is ca. 40 times less active than the uncoated catalyst at peak activity. This Al2O3-overcoated Ni/Al2O3 catalyst also exhibits a long induction period (∼20 h) due to the slow reduction of Ni2+ within the catalytically inactive nickel aluminate (NiAl2O4) phase, formed by the interaction of metallic Ni with the Al2O3 overcoat during pre-DRM treatment at the 700 °C reaction temperature. Here, we report that, while doping small amounts of La (∼0.03 wt %) into the Ni/Al2O3 catalyst does not significantly affect the catalytic activity or stability by itself, the addition of ALD-Al2O3 on top of the La2O3-promoted Ni catalysts significantly suppresses the long TOS deactivation, helps recover the peak activity of uncoated Ni/Al2O3, and eliminates the DRM induction period. This strategy obtains the stabilization benefits of Al2O3 overcoating on Ni/Al2O3 while, at the same time, avoiding the formation of undesirable NiAl2O4 species." @default.
