Synthesis Of Carbon Nanotube Loaded Nano-copper-nickel Alloy

Carbon nanotubes(CNTs)have aroused widespread concern for their unique structure and excellent properties in physical,chemical and mechanical.Fileds copper-nickel alloy(Cu-Ni)is a kind of important conductive metal materials that can be widely used in electric,magnetic,catalytic and many other fields as well.The combination of nanocomposites exhibit excellent comprehensive properties which it make it one of the most promising areas at present.This paper shows the preparation of the work and the test result of carbon nanotubes(CNTs)load the nano copper-nickel alloy(CuNi/CNTs)composite materials that the nano composite can be used as an electrode material and fuel cell.In this paper,carbon nanotubes(CNTs)which were acidized by mixed acid are used as templates to prepare nano copper-nickel alloy(CuNi/CNTs)composite materials.Experiments prove their electrochemical activity is superior to the pure alloy in alkaline solution,and the peak reaches maximum value when alloy is 20wt%.In this thesis the microwave methodwas used to prepare the composite materials which is include nano copper-nickel solid solutioned(Cu/Ni)and carbon nanotubes/nano copper-nickel solid solution(CuNi/CNTs).XRD and XPS analysis are used to characteris the structure of nano copper-nickel solid solution(Cu/Ni),which shows that the nickel(Ni)atoms go into the copper(Cu)lattice and completely replace the copper(Cu)atoms,and only one phase formed means the two substances form a solid solution.The study has not been reperted in the literature at present.According to the test,Carbon nanotubes(CNTs)/nano copper-nickel solid solution(Cu/Ni)have the best electrochemical activity when the glucose concentration is 0.03M.
