Plasma-assisted dry reforming of methane over Mo2C-Ni/Al2O3 catalysts: Effects of β-Mo2C promoter

Yanan Diao et al.

Summary: The addition of beta-Mo2C facilitated charge deposition, leading to the re-dispersion of Ni nanoparticles over the beta-Mo2C surface due to the strong interaction between Ni and beta-Mo2C. The mechanically mixed Mo2C-Ni/Al2O3 catalyst with the new active interface of Ni-Mo2C exhibited much better activity and stability compared to the undoped Ni/Al2O3 catalyst, providing practical solutions to depress carbon deposition and enhance catalytic stability in plasma-assisted DRM reaction.

Oxidative coupling of methane over Y2O3 and Sr-Y2O3 nanorods

Yuqiao Fan et al.

Summary: Y2O3 nanorods were prepared by a hydrothermal method, with Sr-modified Y2O3 nanorods synthesized by an impregnation method. The addition of a small amount of Sr to Y2O3 nanorods enhances the activation of oxygen and the amount of moderate basic sites, improving the oxidative coupling of methane performance. The study found that the C2-C3 yield achieved on the Y2O3-based catalysts correlated well with the amount of moderate basic sites present on the catalysts.

NixAl1O2-δ mesoporous catalysts for dry reforming of methane: The special role of NiAl2O4 spinel phase and its reaction mechanism

Shuangshuang Zhang et al.

Summary: The evolution of the surface NiAl2O4 spinel phase in NixAl1O2-delta mesoporous catalysts synthesized by the citric acid sol-gel method was systematically studied. The constructed Ni-0-NiAl2O4 interfaces and active oxygen species generated by filling oxygen vacancies of NiAl2O4 spinel play important roles in enhancing the stability and resistance to coking and sintering in dry reforming of methane reaction.

Ni-containing CeO2 rods for dry reforming of methane: Activity tests and a multiscale lattice Boltzmann model analysis in two model geometries

Filip Strnisa et al.

Summary: Experimental and theoretical modeling of low-temperature dry methane reforming over Ni-containing CeO2 rods was conducted, with characterization studies revealing distortion of CeO2 structure due to Ni incorporation. Various techniques were used to characterize the catalyst, and activity tests showed similar trends in two model geometries. The lattice Boltzmann model developed for mixed gas flow was used in multiscale simulations and qualitatively matched experimental data.

Superior 3DOM Y2Zr2O7 supports for Ni to fabricate highly active and selective catalysts for CO2 methanation

Xiuzhong Fang et al.

Summary: A novel CO2 methanation catalyst using 3DOM structured Y2Zr2O7 pyrochlores as support for NiO/Ni was prepared, showing stronger interaction between NiO and 3DOM supports compared to traditional Y2Zr2O7-CP supports. The unique structure provided more active Ni surface and surface active O2- / alkaline sites, leading to superior reaction performance surpassing existing literature reported catalysts.

Raman spectroscopy of the Al-doping induced structural phase transition in LaCrO3 perovskite

R. S. Silva Jr et al.

Summary: The structural phase transition induced by Al doping in LaCr1-xAlxO3 solid solution was carefully investigated using Raman Spectroscopy. The experimental results show that as the Al content increases, the transition from orthorhombic to rhombohedral structure is accompanied by a decrease in intensity and displacement of vibrational modes. This suggests that above a certain threshold, Al doping in LaCrO3 leads to instability and structural distortions that trigger the structural phase transition.

Coking-resistant dry reforming of methane over Ni/γ-Al2O3 catalysts by rationally steering metal-support interaction

Bo Yang et al.

Summary: The enhanced coking resistance of bound Ni in Ni/γ-Al2O3 catalysts for dry reforming of methane is attributed to its ability to facilitate CO desorption, suppress CO disproportionation, and reduce carbon deposition. Bound Ni exhibits higher activity due to its better methane cracking ability, stronger adsorption, and activation of CO2 by forming polydentate carbonate. The superior activation of CO2 by bound Ni also contributes to the gasification of formed coke.
