Significantly improved hydrogen storage behaviors in MgH2 with Nb nanocatalyst
The study explores the excellent modification effect of Nb nanocatalyst prepared via surfactant assisted ball milling technique (SABM) on the hydrogen storage properties of MgH 2 . Optimal catalyst doping concentration was determined by comparing onset decomposition temperature, released hydrogen ca...
