Ball-milling preparation of titanium/graphene composites and its enhanced hydrogen storage ability

Ti nanoparticles wrapped in graphene (Ti/GE) composites have been synthesized by a simple ball-milling method. Ti-C bonding is formed on the interface of Ti nanoparticles and graphene and Kubas-typed interaction with hydrogen is verified. The Ti/GE composites achieve an enhanced hydrogen storage (4.3 wt% for H2 at 300 °C, 0.08 bar).302
