Preparation,characterization And Property Of Indium(Nickel)phosphide/rGO Composite

In this paper,the InP/rGO composites was prepared by solvothermal method successfully.Composite materials by condition experiment to controlled synthesis of different morphologies,and the different composite material was studied on electrochemical performances,and the reaction mechanism of lithium-ion battery were also discussed.The main contents are summarized as follows:?1?InP/rGO composites were synthesized by CTAB assisted,and characterized by XRD,EDS,SEM,TEM test,to analysis the test results,we can find that InP/rGO composite were prepared successfully.In the process of solvothermal,graphene oxide has been reduced into rGO,the composite material prepared in this experiment were combined with the rGO sheet and InP microspheres,and InP microspheres anchored on the surface of rGO,forming a stable composite material.Through the lithium chemical performance test of single material and the composite materials,we can find that after combine with the rGO,the lithium chemical properties of InP has been significantly enhanced,in the current density of 50 mA/g,the initial discharge capacity was 1519.83 mAh/g,the initial coulombic efficiency was 69.23%.After 100 cycles,the discharge capacity still maintain at 820.57 mAh/g.The results show that the charge / discharge capacity of the In P has been greatly improved after combine with rGO,and the cycle performance was stability and rate performance have been improved.?2?Indium phosphide/rGO composites were successfully prepared by solvothermal method and characterized by XRD,SEM and TEM.The test results showed that in the composite material,InP was tetragonal phase structure,and the product was crystalline commendably,indiumphosphide particles grow on the surface of rGO averagely.By the controlled the addition of graphene oxide,we obtained different content of rGO products,and the morphology of the products were characterized,three kinds of samples were tested by lithium chemical performance and the results showed that the sample with 5 mg GO added showed the best performance.By testing the single material and we find that the composites as anode materials for lithium-ion batteries showed a higher capacity than that of and the single material and the cycle performance was relatively stable,higher coulombic efficiency,well reversibility.?3?By using the mixed solvothermal method the Ni₂P/rGO nano-composite was synthesis successfully,the structure and morphology of the products were characterized by XRD,EDS,SEM,TEM and HRTEM,the result showed that Ni₂ P nanoparticles were uniformly grown on the surface of rGO,forming a stable microstructure,the size of Ni₂ P on surface of rGO was 30-50 nm.The adsorption / degradation experiments indicating that by adsorption / degradation of several organic dyes photocatalytic experiment,Ni₂P/rGO nano-composite had good adsorption and photocatalytic degradation of helianthin B,methylthionine chloride,rhodamine B,pyrrole-red,the degradation rate reached more than 90%.The chemical properties of lithium-ion battery test results showed that by combine with rGO,the defects of single material was improved effectively,lithium chemical properties of composite was better than that of the single material and composite material not only showed the high initial discharge capacity was relatively,but also showed a very good cycle stability at the different current density.
