Dry Reforming of Methane over Pyrochlore-Type La₂Ce₂O₇-Supported Ni Catalyst: Effect of Particle Size of Support

Molecules
The properties of supports (such as oxygen vacancies, oxygen species properties, etc.) significantly impact the anti-carbon ability due to their promotional effect on the activation of CO2 in dry reforming of methane (DRM).
