This study investigates the effect of activation environment on the catalytic performance of heterogeneous nanostructured catalysts based on FePt bimetallic nanoparticles supported on layered hexagonal boron nitride h-BN in carbon monoxide oxidation reactions. The material's structure was characterized by transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), and energydispersive Xray spectroscopy (EDS) elemental mapping. The surface chemical state of activated samples was analyzed using Xray photoelectron spectroscopy (XPS). The results demonstrate that the choice of activation environment (hydrogen/helium) strongly affects the CO conversion temperature. Keywords: nanomaterials, catalysis, CO oxidation, activation.
