dc.description.abstractThe heat treatment of alloy nanoparticles to improve their catalytic properties generally results in severe sintering. In this study, we report a new synthetic process of silica encapsulation to inhibit the sintering of Pt3Co1 alloy particles during heat treatment at high temperature. The silica layer acts as a physical barrier to prevent sintering-
dc.description.abstractthus, the carbon-supported Pt3Co1 alloy nanoparticles retained their small particle size after heat treatment. The heat treatment allows the atoms to rearrange themselves, which results in a Pt-rich surface of the alloy nanoparticles. As a result, catalytic activity and stability were improved significantly.-
