Peparation of Bi2Te3-polyaniline Heterostructured Nanorods by Two-step Electrochemical Depositions
二次电化学沉积法制备聚苯胺-碲化铋复合纳米棒

We succeeded in the fabrication of polyananiline/Bi2Te3 heterostructured nanorods by means of two-step electrochemical depositions from aqueous solution. In the first step, polyaniline nanotubules were electrodeposited in alumina template. In the second step, using conducting polyaniline nanotubules as template, Bi2Te3 nanorods were electrodeposited. Characterizations of XRD indicate that the deposited Bi2Te3 rods are highly textured in the {110} direction. Furthermore, FESEM and TEM analysis show that the Bi2Te3 nanorods are well enveloped in polyaniline tubules in pores of alumina template. The two-step electrodeposition method provides a promising path for fabricating organic-inorganic heterostructured nanorods.
