Enhanced CO Oxidation Activity of Ni@Ag Core–Shell Nanoparticles

Enhanced CO Oxidation Activity of Ni@Ag Core–Shell Nanoparticles

Ni@Ag core–shell nanoparticles supported on SiO2 were prepared by a galvanic replacement reaction between Ni and Ag at a low temperature (213 K). The Ni@Ag core–shell catalyst showed a higher catalytic activity for CO oxidation than Ag and Ni monometallic catalysts as well as than Ni–Ag bimetallic c...

description Ni@Ag core–shell nanoparticles supported on SiO2 were prepared by a galvanic replacement reaction between Ni and Ag at a low temperature (213 K). The Ni@Ag core–shell catalyst showed a higher catalytic activity for CO oxidation than Ag and Ni monometallic catalysts as well as than Ni–Ag bimetallic catalyst prepared by a conventional impregnation method.
