Gaseous and Electrochemical Hydrogen Storage Properties of Mg-Based Thin FilmsThis thesis introduces the preparation of a series of Mg based thin films with different structures using magnetron sputtering, as well as the systematical investigation of their gaseous and electrochemical hydrogen storage properties under mild conditions. It reviews promising applications of Mg based thin films in smart windows, hydrogen sensors and Ni MH batteries, while also providing significant insights into research conducted on Mg based
