Abstract

Here, we report the microstructural and hydrogen storage properties of a 40-layer film of Pd (x nm)/Ti (40 nm)/Mg (360 nm)/Ti (40 nm) (x = 0, 5, 10, and 20) fabricated using an ultra-high vacuum DC magnetron sputtering system. The superior hydrogen uptake of the Pd/Ti/Mg/Ti films was 6.42 wt. % for x = 10 at 150 °C. The hydrogen absorption time is strongly dependent on the Pd film thickness (0-40 nm). As a result, the Pd/Ti/Mg/Ti multilayer film with the Pd interlayer can be attributed to offer the further diffusion channels and the controlled growth rate of hydride formation at the Pd/Ti/Mg interfaces, which provides an overall enhancement of the hydrogen storage properties.
