Cu₃N@ ZnAl-LDH 纳米线阵列材料的制备及其电化学特性

Using copper foam as raw material, the nanowire array with Cu₃N as core and ZnAl layered dihydroxide (ZnAl-LDH) as shell were prepared by alkaline oxidation etching, ammonia annealing and alternating dipping method. The effect of preparation process on the morphology of the nanowire array and its intermediate products was studied. And electrochemical properties of Cu₃N@ZnAl-LDH nanowire arrays was also investigated. The results show that the Cu₃N@Znal-LDH nanowires array combines the structural characteristics of porous, ultra-thin two-dimensional LDH shell and highly conductive one-dimensional Cu₃N core, and exhibits high unit surface capacitance and high energy density, It is expected to be used as electrode material for high-performance supercapacitors in the future.
