Synergistic Promotion of Ni/La2O3 Catalysts by Copper for Efficient Dry Reforming of Methane
Greenhouse Gases: Science and Technology, Volume 15, Issue 5, Page 542-557, October 2025.ABSTRACT The catalytic performance of Ni/La2O3 and Ni–Cu/La2O3 for dry reforming of methane (DRM) was investigated, focusing on reducibility, stability, and coke resistance. Cu incorporation lowered the Ni reduction temperature, as revealed by temperature‐programmed reduction (TPR), enhancing hydrogen spillover and oxygen vacancy formation.
