Abstract

Pd/Al₂O₃ catalysts were prepared using various Al₂O₃ supports with different structural features such as crystalline phase and crystallinity related to Al³⁺ coordination, revealing a significant insight into the methane (CH₄) combustion activity of Pd nanoparticles with the fraction of penta-coordinated Al³⁺ sites in the Al₂O₃ supports.
