- Abstract
Co2P nanoparticles, obtained by a simple mechanical ball-milling treatment, have been shown to undergo a new hydrogen adsorption-transmission process called intracell Kubas-enhanced adsorption, which results in an improved hydrogen-storage capacity. It is found that in this intracell Kubas-enhanced adsorption process hydrogen is firstly adsorbed by the Co atoms in Co2P through a Co ···H interaction and activated. It is then spilt over to the P atoms in Co2P accompanied by the formation of a P-H bond, which has a lower bonding energy. This adsorption-transmission process is unambiguously proved by a detailed analysis of X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD), cyclic voltammetry (CV), and quantum chemical calculation results.
