Title: Enhanced activity and stability of MgO-promoted Ni/Al₂O₃ catalyst for dry reforming of methane: Role of MgO

Abstract

Highly dispersed nickel nanoparticles (NPs) were deposited on Al2O3 NPs by atomic layer deposition (ALD). Various amounts of MgO were loaded on Ni/Al2O3 catalysts by the incipient wetness (IW) method for dry reforming of methane. Fresh and used catalysts were systematically characterized to reveal the effects of MgO on the catalytic performance. MgO was found to increase the basic amount and basic strength of catalyst surfaces, which provided additional surface oxygen species and assisted the adsorption and activation of CO2. Although the formation of NiO-MgO solid solution, during the calcination of incipient wetness, did not improve the overall reducibility, the Ni NPs from NiO-MgO solid solution after reduction formed an intimate interaction with MgO, which could inhibit Ni NPs from sintering and provide sufficient metal-support interface for CO2 activation. The MgO-promoted Ni/Al2O3 reached a methane reforming rate of 1780 LCH4gNi-1 h-1 at 850 °C, which is 26% more than that of the pristine Ni/Al2O3. The higher CO2 activity enhanced the oxidation rate of the surface carbon generated from side-reactions, thereby resulting in a higher reforming rate and inhibiting coke formation, especially the detrimental graphitic encapsulating carbon on an active nickel surface.

Reforming of methane with carbon dioxide over cerium oxide promoted nickel nanoparticles deposited on 4-channel hollow fibers by atomic layer deposition

Journal Article Jin, Baitang ; Shang, Zeyu ; Li, Shiguang ; ... - Catalysis Science and Technology

Ni nanoparticles were deposited on four-channel structured α-Al2O3 hollow fibers by atomic layer deposition (ALD). CeO2 was loaded by a liquid phase incipient wetness method to promote Ni catalysts for dry reforming of methane. For Ni/Al2O3 prepared by ALD, inactive NiAl2O4 that originated from the Ni ALD process was incompletely reduced. The introduced CeO2 was found to weaken the NiO-Al2O3 interaction, free NiO from NiO-Al2O3 or NiAl2O4, and improve the reducibility of NiO. The higher reducibility of NiAl2O4, tuned by CeO2, further activated the catalyst during DRM, because a larger proportion of NiAl2O4 was gradually reduced to metallic nickel bymore »« less

Journal Article Gould, Troy D. ; Montemore, Matthew M. ; Lubers, Alia M. ; ... - Applied Catalysis. A, General, 492:107–116

Atomic layer deposition (ALD) was used to deposit Ni and Pt on alumina supports to form monometallic and bimetallic catalysts with initial particle sizes of 1–2.4 nm. The ALD catalysts were more active (per mass of metal) than catalysts prepared by incipient wetness (IW) for dry reforming of methane (DRM), and they did not form carbon whiskers during reaction due to their sufficiently small size. Catalysts modified by Pt ALD had higher rates of reaction per mass of metal and inhibited coking, whereas NiPt catalysts synthesized by IW still formed carbon whiskers.

Engineering metal-oxide interface by depositing ZrO₂ overcoating on Ni/Al₂O₃ for dry reforming of methane

Journal Article Jin, Baitang ; Li, Shiguang ; Liu, Yuzi ; ... - Chemical Engineering Journal

Zirconium oxide (ZrO2) was deposited onto Ni/Al2O3 catalyst as overcoating by atomic layer deposition (ALD) for dry reforming of methane (DRM). High-temperature heating during H2-reduction could transform the ALD-prepared ZrO2 thin film to tetragonal phase and crack the encapsulating layer on Ni sites, which constructed a beneficial Ni-ZrOx interface. Interfacial surface oxygen vacancies on ZrO2 overcoating were induced by the partial reduction of ZrO2 surface during high-temperature H2 reduction, with the assistance of Ni. During DRM, the interfacial oxygen vacancies enhanced CO2 activation by dissociating CO2 and releasing active O, thereby limiting carbon formation. For DRM at 800 °C andmore »« less

Nano–engineered nickel catalysts supported on 4–channel α–Al₂O₃ hollow fibers for dry reforming of methane

Journal Article Shang, Zeyu ; Li, Shiguang ; Wang, Qingfa ; ... - AIChE Journal

A nickel (Ni) nanoparticle catalyst, supported on 4‐channel α‐Al ₂ O ₃ hollow fibers, was synthesized by atomic layer deposition (ALD). Highly dispersed Ni nanoparticles were successfully deposited on the outside surfaces and the inside porous structures of hollow fibers. The catalyst was employed to catalyze the dry reforming of methane (DRM) reaction and showed a methane reforming rate of 2040 Lh ⁻¹ gNi ⁻¹ at 800°C. NiAl ₂ O ₄ spinel was formed when Ni nanoparticles were deposited on alpha‐alumina substrates by ALD, which enhanced the Ni‐support interaction.

Nano-Engineered Catalyst Supported on Ceramic Hollow Fibers for the Utilization of CO₂ in Dry Reforming to Produce Syngas

Technical Report Liang, Xinhua ; Jin, Baitang ; Li, Shiguang ; ...

The objective of this project was to develop a novel catalytic reactor containing nano-engineered catalysts for the utilization of CO₂ (captured from coal-fired power plants and other CO₂ emitting sources) in dry methane reforming (DMR) (CO₂ + CH₄ → 2 H₂ + 2 CO) to produce synthesis gas (syngas). The technology aims to reduce CO2 emissions by developing beneficial uses for CO₂ from coal-fired power plants. It also offers an alternative to mitigate CO₂ emissions in areas where geologic storage may not be an optimal solution and/or utilization could significantly offset the costs of carbon capture and sequestration.
