In a typical procedure, highly ordered AAO membranes were prepared by a two-step anodization from the 99.9% aluminum foil as described elsewhere in detail [12]. The templates had a thickness about 20 mm and a diameter around 200 nm. A thin layer of Au with thickness of about 10 nm was sputtering deposited onto one side of the templates serving as the working electrode. The precursor electrolytes for the deposition of BSPT NTs contained a MPB
composition of 0.36BiScO3e0.64PbTiO3 (5 mol% Pb excess) via an aqueous solegel method [13]. Electrodeposition process was
