| dc.description.abstract | gamma-Al2O3-supported Pt group catalysts are widely used in many industrially important catalytic processes. However, gamma-Al2O3-supported Pt catalysts are prone to deactivation via metal sintering at high temperatures, in oxidative reaction environments, or both. Using a combination of experimental HRTEM and EXAFS measurements and theoretical DFT calculations, we find that pentacoordinated Al3+ sites (Al-p) on the gamma-Al2O3(100) surface can inhibit Pt sintering both thermodynamically and kinetically because of their strong interactions with atomic Pt or Pt oxide species. The present work suggests a promising approach for stabilizing the size and morphology of supported catalytically active phases | - |
