The obtained X-ray diffraction pattern and transmission electron microscopy images correspond to PtxCoy alloy nanoparticles with average diameters of 2.4 nm and well-established crystalline structure. The synthesized PtxCoy/C catalyst containing 1.5 wt% of PtxCoy nanoparticles can achieve complete CO conversion in the temperature range 125–175°C working at weight hourly space velocities (WHSV) of 30 L h-1g-1. 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.2018http://zaguan.unizar.es/record/7545110.3389/fchem.2018.00487http://zaguan.unizar.es/record/75451oai:zaguan.unizar.es:75451info:eu-repo/grantAgreement/ES/ISCIII/CIBER-BBNinfo:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010Frontiers in chemistry 6 (2018), 487 [10 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
