摘要
Using Density Functional Theory (DFT), the desorption energies of Hydrogen in Aluminum, and Boron nanoparticles (NPs) is calculated. The type of NPs studied here, were MnHm with M = Al or B, n varying from 2 up to 20 and m/n between 0 and 3. NPs combining the two atoms (Aln-xBxH3n) were also examined. These types of clusters combine the low weight of B with the low desorption energies of Al. For each NP, several different geometries were studied in order to find the one with the lowest energy.
