Adsorption of molybdenum blue nanoparticles on the alumina surface

The paper presents the results of the adsorption study of the molybdenum blue nanoparticles (a precursor of catalytically active molybdenum carbide) on the alumina surface of different phase composition. It is shown that upon contact, a specific interaction occurs between nanoparticles and the surface of alumina, and the pH value has a significant effect on the quantitative parameters of adsorption. The processing of adsorption data using the Langmuir equation made it possible to estimate the value of the capacity of a monolayer and the surface occupied by 1 nanoparticle of molybdenum blue. Based on the results obtained, the conditions for obtaining catalysts based on molybdenum carbide with a different distribution of the active component in/on the support were established.
