Significance The use of hydrogen peroxide (H 2 O 2 ) for catalytic oxidations is limited by the energy-intensive and wasteful process by which H 2 O 2 is currently produced—the anthraquinone process. The direct synthesis of H 2 O 2 (DSHP) is a promising alternative process, yet catalysts active for this reaction (Pd being the most widely studied) are generally hindered by subsequent H 2 O 2 decomposition. Through a combined theoretical and experimental approach, our work ( i ) provides an understanding of the nature of Pd active sites responsible for H 2 O 2 decomposition and ( ii ) identifies a single type of elementary step that controls the rate. These structural and mechanistic insights are important for designing improved DSHP catalysts and for developing transition-metal–catalyzed oxidations that efficiently use H 2 O 2 .
