Abstract: We construct a catalytic system comprising Ni0 and Ni phyllosilicate, bridged by a Niδ+-O-Si interfacial structure. The resulting strong metal-support interactions (SMSI) anchor Ni nanoparticles against sintering, while the Ni0/Niδ+-O-Si synergy promotes efficient CO 2 and CH 4 co-conversion. [Display omitted] • Formation of Niδ+-O-Si interfaces between Ni0 nanoparticles and the Ni phyllosilicate. • The Ni 0.45 Si 0.55 O δ catalyst demonstrates superior dry reforming of methane performance. • Strong metal-support interaction between Ni0 and Niδ+-O-Si ensures outstanding sintering resistance over 300 h. • Ni0 and Niδ+-O-Si dual sites synergistically activate CH 4 and CO 2. Dry reforming of methane (DRM) is pivotal for carbon recycling. However, its industrial deployment is hindered by the trade-off between activity decline and insufficient stability in Ni-based catalysts, caused by sintering under prolonged high temperature conditions. Herein, we developed the Ni x Si 1-x O δ (x = 0.30–0.50) catalysts coupled interfaces between Ni0 particles and Niδ+-O-Si species. The Ni 0.45 Si 0.55 O δ catalyst exhibits outstanding DRM performance at 750 °C, achieving CH 4 and CO 2 conversions of 93.6% and 94.7%, respectively. It concurrently demonstrates exceptional stability over 300 h long-term test, successfully overcoming the trade-off. The Ni phyllosilicate structure facilitates the formation of highly dispersed Ni0 particles anchored on Niδ+-O-Si interface, inhibiting Ni particle sintering and enhancing the long-term stability by interfacial strong metal-support interactions (SMSI). In situ DRIFTS experiments corroborate a dual-site synergistic mechanism, where Ni0 sites activate CH 4 , and adjacent Niδ+-O-Si interfaces facilitate CO 2 activation. This work proposes a novel microstructure regulation strategy to break the trade-off between Ni particles sintering and CH 4 /CO 2 conversion activity by Strong metal-support interaction of Ni0 and Niδ+-O-Si. It provides a new design principle for developing high performance DRM catalysts that balance the activity and stability. [ABSTRACT FROM AUTHOR]
