中文摘要	Platinum nanowire array sensors were prepared by alternating current electrochemical deposition of platinum into the pores of anodic aluminum oxide template. The nanostructure displayed perfect electrochemical stability with 10 segments of the cyclic voltammetry curves coincided completely, and the oxide-current peak of H2O2 was in the range of 0.3-0.6 V. Moreover, the response current has an excellent linear relationship with the H2O2 concentration at the range from 4.5 x 10(-3) mM to 2.3 x 10(-1) mM, and the detection limit was about 0.56 mu M. After dissolving AAO template in 0.3 M KOH for 20 min, the sensitivity of the sensor was increased from 34.76 mu A mM(-1) mm(-2) to 62.35 mu A mM(-1) mm(-2), and the detection limit was lowered from 0.56 mu M to 0.28 mu M. Furthermore, the platinum nanowire array sensors presented good stability and repeatability.
