Graphite-titanium-nanocomposite complex and method of preparation thereof

A method of preparing a graphite-titanium-nanoparticle complex, the method comprising:

• amine functionalizing of graphite by a coupling agent to produce amine functionalized graphite, wherein the amine functionalizing occurs in an atmosphere of noble gas for a time period of six hours;
• amine functionalizing of titanium by a coupling agent to produce amine functionalized titanium, wherein the amine functionalizing occurs in an atmosphere of noble gas for a time period of six hours;
• mixing the amine functionalized graphite with the amine functionalized titanium using a vortex shaker to produce a mixture, wherein the mass ratio of amine functionalized graphite to amine-functionalized titanium is 1:1;
• synthesizing an ion complex by adding a metal ion solution to the mixture, the metal ion solution and mixture undergoing gentle shaking at a temperature of 80° C. for a time period ranging from twelve to thirty-six hours;
• and
• adding freshly prepared trisodium citrate solution and sodium borohydride solution to the ion complex in a shaker for a time period of one hour at room temperature to produce a graphite-titanium-nanoparticle complex, wherein the mass ratio of trisodium citrate solution to sodium borohydride is 1:1.
