摘要：

In the present study, hydrogen absorption/desorption properties of porous hollow palladium spheres prepared by templating method were studied. The experimental results reveal that porous hollow Pd spheres have superior hydrogen absorption kinetics than spongy Pd. A typically pressure hysteresis behavior can also be observed in the hydrogen absorption/desorption isotherm curves. Gibbs free energy loss Delta G(loss) correlation with pressure hysteresis of porous hollow Pd spheres is 4.3-4.8 kJ/mol, which is larger than spongy Pd and Monocrystal Pd. The special hollow structure and microstructure defects of Pd powder should be taken into account. Moreover, hydride formation enthalpy of porous hollow Pd spheres is smaller than spongy Pd and Pd black. (c) 2016 Elsevier B.V. All rights reserved.
