Strong metal‒support interaction modulates catalytic activity of Ru nanoparticles on Gd₂O₃ for efficient ammonia decomposition.

ABSTRACT: Exploration of efficient Ru-based catalysts is significant for advancing the production of hydrogen from ammonia decomposition, which depends predominantly on the rational regulation of the metal-support interaction of Ru-based catalysts. Herein, highly dispersed Ru nanoparticles (NPs) on Gd₂O₃ (Ru/Gd₂O₃) are developed and applied for the NH₃ decomposition reaction. By varying the reduction temperature, the activity of the Ru/Gd₂O₃ catalyst can be remarkably improved. Characterization results reveal that the enhanced activity is associated with the strong metal‒support interaction (SMSI) induced formation of Gd₂O₃ overlayer on the Ru NPs. With a relatively low reduction temperature, the expos
