A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

open access: yesEcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...
