摘要
The cohesive energy of metallic nanoparticles has been studied by Lennard-Jones potential. It is found that the Lennard-Jones potential can be used to calculate the cohesive energy of metallic nanoparticles by considering the size-dependent potential parameters. It is predicted that the cohesive energy of small particles decreases with decreasing the particle size, which is consistent with the experimental values of Mo and W nanoparticles.
