Abstract: 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 energy-dispersive X-ray spectroscopy (EDS) elemental mapping. The surface chemical state of activated samples was analyzed using X-ray photoelectron spectroscopy (XPS). Results demonstrate that the selection of activation environment (hydrogen/helium) significantly affects the CO conversion temperature.

Keywords: nanomaterials, catalysis, CO oxidation, activation.
