High performance and stable mesoporous MgO–ZrO2 supported Ni catalysts for dry reforming of methane
Catalysts for dry reforming of methane (DRM) based on Ni are used widely. However, due to carbon deposition or active metal sintering, deactivation is inevitably attached to these catalysts. Ni catalysts supported on mesoporous MgO–ZrO2 have been synthesized by surfactant-assisted route and impregna...
