A study on the thermodynamic stabilities of Li-and Na-decorated 2D boron phosphide (BP) systems found that the dispersed Li and Na atoms on the monolayer surface significantly increase both the H2 binding energies and the H2 storage capacities. An improvement in hydrogen-storage capacity due to the process of intracell Kubas-enhanced hydrogen adsorption in Co2P nanoparticles obtained by ball-milling has also been discovered. 117
