Synthesis of titanium-decorated graphene for renewable energy applications

Reduced graphene oxide (RGO) was prepared from natural graphite by Hummers’ Method. Few-layer graphene was decorated with titanium by an incipient wetness impregnation method. The pristine graphene shows hydrogen storage capacity equal to 1.3 wt%, while graphene decorated by titanium (RGO–Ti) enhanced hydrogen storage capacity to 1.4 wt%. We showed that titanium addition improved hydrogen storage capacity by chemical interactions. These interactions can be used for fabrication of different graphene-based materials as potential candidates for developing new absorbents for energy application
