HighlightsThe SiO 2 overlayer of Pt-SiAl@ Si is bifunctional.SiO 2 shell as a physical barrier has an ability to retard sintering of Pt nanoparticles.Pt-acid sites interfaces arising from interaction between SiO 2 shell and support enhanced the oxidation-resistance of Pt 0.The increased acidity of catalyst promoted the fast desorption and decomposition of nitrate species, facilitating NO oxidation.
