Influence of Adhesion on the Chemical Potential of Supported Nanoparticles as Modeled with Spherical Caps

Philipp N. Plessow et al.

Summary: The study examines the impact of adhesion on the chemical potential of supported nanoparticles, showing that the chemical potential is influenced by adhesion energy and particle volume. The use of hemispherical particle shape provides a good approximation for the chemical potential, with an error of less than 10% for contact angles between 66 and 120 degrees.

Size-Dependent Energy of Ni Nanoparticles on Graphene Films on Ni(111) and Adhesion Energetics by Adsorption Calorimetry

John R. Rumptz et al.

Summary: The use of carbon supports for late transition-metal nanoparticle catalysts has increased in recent years. However, there is limited understanding of the bonding energetics between metal nanoparticles and carbon supports. In this study, the growth morphology and heats of adsorption of Ni on graphene/Ni(111) were investigated, providing insights into Ni chemical potential and Ni/graphene adhesion energy.

Nature of the Active Sites on Ni/CeO2 Catalysts for Methane Conversions

Pablo G. Lustemberg et al.

Summary: Research has shown that cationic Ni atoms in clusters at step edges on the CeO2(111) surface are the most active sites for methane conversion reactions, with their small size and high Ni chemical potential contributing to their activity. Density functional theory calculations have clarified the reasons behind this observation, highlighting the importance of the size and morphology of supported Ni nanoparticles, strong Ni-support bonding, and charge transfer at step edges for high catalytic activity, particularly in the activation barrier for C-H bond cleavage during CH4 dissociative adsorption. This knowledge is expected to inspire the development of more efficient catalysts for these reactions.

Predicting a Key Catalyst-Performance Descriptor for Supported Metal Nanoparticles: Metal Chemical Potential

Zhongtian Mao et al.

Summary: The chemical potential of metal atoms in supported nanoparticles serves as a convenient descriptor for their performance as heterogeneous catalysts, influenced by particle size, support, and alloying. Microcalorimetric measurements reveal that the chemical potential can be predicted based on monometallic particle diameter and the adhesion energy of the particle to the support. These findings suggest potential improvements in the Gibbs-Thomson relation for free-standing nanoparticles.
