One-Pot Synthesis of Full-Featured Mesoporous Ni/Al2O3 Catalysts via a Spray Pyrolysis-Assisted Evaporation-Induced Self-Assembly Method for Dry Reforming of Methane

Jeong-Cheol Seo et al.

Summary: This study successfully prepared mesoporous supported nickel catalysts with high activity and stability in DRM reaction through a one-pot synthesis method. By using spray pyrolysis-assisted evaporation-induced self-assembly, the catalysts with highly dispersed nickel active sites were obtained in one step. Furthermore, the performance of nickel catalysts was further optimized by employing phase segregation and exsolution strategies.

Atomic level fluxional behavior and activity of CeO2-supported Pt catalysts for CO oxidation

Joshua L. Vincent et al.

Summary: This study used electron microscopy to observe the structural dynamics occurring at and near Pt/CeO2 interfaces during CO oxidation, showing that catalytic turnover frequency correlates with fluxional behavior. This behavior destabilizes supported Pt particles, enhances oxygen vacancy creation and annihilation rates, leads to increased strain and reduction in CeO2 support surface.

A review on dry reforming of methane over perovskite derived catalysts

Srikar Bhattar et al.

Summary: Perovskite-derived catalysts in dry reforming of methane exhibit superior catalytic performance due to the synergistic effects of bimetallic addition at the B site and enhanced oxygen mobility through A site substitutions. The use of high surface area supports also greatly influences the physicochemical and catalytic behavior of perovskite-derived catalysts. The exsolution process involved in the reduction of perovskite catalysts produces smaller size metal particles which dictate the superior catalytic performance of these materials.

Role of lattice oxygen in methane activation on Ni-phyllosilicate@Ce1-xZrxO2 core-shell catalyst for methane dry reforming: Zr doping effect, mechanism, and kinetic study

Sonali Das et al.

Summary: Sandwich structured core-shell Ni-Phyllosilicate@Ce1-xZrxO2 catalysts with optimal Zr loading in the Ce1-xZrxO2 shell are found to greatly enhance the intrinsic activity for DRM due to increased lattice oxygen mobility of the ceria-zirconia shell and stronger metal-support interaction with Ni. Involvement of lattice oxygen in methane activation and dissociation contributes to the higher DRM activity of the Zr-doped catalyst with maximum oxygen storage capacity, as inferred from rigorous kinetic and mechanism studies.

Intensifying chemical looping dry reforming: Process modeling and systems analysis

Hari C. Mantripragada et al.

Summary: This paper explores the use of chemical looping dry reforming (CLDR) to intensify dry reforming of methane by improving its carbon balance and energy efficiency, producing separated syngas streams. Performance models compare different process configurations for supplying heat needed for the reforming reaction, showing that CLDR processes can significantly exceed conventional dry reforming in terms of syngas yield and CO2 utilization. The internal carbon combustion configurations showed the highest efficiency, demonstrating the potential for innovative process designs enabled by chemical looping schemes.

Highly active and coke resistant Ni/CeZrO2 catalyst prepared by cold plasma decomposition for CO2 reforming of methane

Yuxiao Dai et al.

Summary: By decomposing nickel precursor with dielectric barrier discharge plasma, the activity of ceria-zirconia solid solution supported nickel catalysts can be improved, resulting in smaller nickel nanoparticles, higher reducibility, more basic sites, and oxygen vacancies. This leads to enhanced activation of CO2 for reforming and improved coke resistance.

Effects of spatially confined nickel nanoparticles in surface-pretreated hydrophobic SBA-15 for dry reforming of CH4 with CO2

Kyung Soo Park et al.

Summary: Efficient methods for preserving smaller nickel nanoparticles on a highly ordered mesoporous SBA-15 were investigated for high temperature dry reforming of methane with CO2. The spatial confinement of nickel nanoparticles in the SBA-15 channels resulted in suppressed thermal aggregation, less coke deposition, and higher catalytic activity. A surface-pretreated SBA-15 with two-step treatment showed a higher dispersion of stabilized nickel nanoparticles in the ordered mesoporous inner channels.
