Data_Sheet_1_Laser-Assisted Production of Carbon-Encapsulated Pt-Co Alloy Nanoparticles for Preferential Oxidation of Carbon Monoxide.pdf

<p>C-encapsulated highly pure Pt<sub>x</sub>Co<sub>y</sub> alloy nanoparticles have been synthesized by an innovative one-step in-situ laser pyrolysis. The obtained X-ray diffraction pattern and transmission electron microscopy images correspond to Pt<sub>x</sub>Co<sub>y</sub> alloy nanoparticles with average diameters of 2.4 nm and well-established crystalline structure. The synthesized Pt<sub>x</sub>Co<sub>y</sub>/C catalyst containing 1.5 wt% of Pt<sub>x</sub>Co<sub>y</sub> nanoparticles can achieve complete CO conversion in the temperature range 125–175°C working at weight hourly space velocities (WHSV) of 30 L h<sup>−1</sup>g<sup>−1</sup>. This study shows the first example of bimetallic nanoalloys synthesized by laser pyrolysis and paves the way for a wide variety of potential applications and metal combinations.</p>
