✦ Synopsis

The influence of Ti on the structural and hydrogen absorption-desorption properties of Laves phase Ho 1-x Ti x Co 2 (x = 0-0.6) alloys have been studied using X-ray diffraction (XRD), pressure-composition (PC) isotherms, differential scanning calorimetry (DSC) and thermogravimetry (TG). The crystalline nature and lattice expansion of hydrogenated alloys at different hydrogen concentrations have been reported. In addition, the coexistence of two hydride phases at intermediate hydrogen concentrations has been identified from the XRD. The changes in plateau pressure and hydrogen absorption-desorption capacity upon increasing Ti content have been discussed. The preferential occupation of different types of interstitial sites has been identified from the DSC studies of hydrides. The complete desorption temperature of hydrogen has been obtained from the TG studies of hydrides.
