The highly active species of Pd/Al2O3 catalysts for methane combustion was revealed by in situ time‐resolved dispersive X‐ray absorption fine structure (DXAFS) spectroscopy. By using CH4 as a reduction agent, PdO in Pd/Al2O3 is reduced in a 2‐step model involving Pd0 nucleation and growth of Pd0 domain in a PdO particle. Kinetic analysis of the 2‐step model reduction of PdO nanoparticles leads to a suggestion that partial formation of Pd^0 in a PdO particle accelerates methane combustion.
