Abstract
Order nanopore arrays were made by a two-step anodization process. The effect of temperature on the order of nanopore arrays was studied. The result shows that the order is bad when the temperature is too high or too low. Then deposit Ni nanowire arrays in nanopores of AAO templates by direct current deposition. Nanowires deposited in AAO template have uniform length and thickness and the shape of nanowires is the same with that of nanopores. And the growth of the nanowires is from the bottom of the nanopores. Finally, the effect of pore diameter on activation energy of nickel deposited in nanopores was studied. The results show that the smaller the pore diameter the smaller the reaction activation energy, that is more conducive to the reaction.
