Effect of particle size and microstructure on the hydrogen storage property in a V-Ti-Cr solid solution system

► V-Ti-Cr nano-particles were prepared via the electric explosion of wire. ► Two kinds of particles with different size were formed. ► Hydrogen storage capacity of nano-particles decreased due to increased surface area. ► Plateau pressure was higher in the particle with smaller lattice parameter. ► Hysteresis in P-C isotherm was larger in the particle with lower strain.
