摘要
Hierarchical nanocomposites of single-crystalline CuO nanoplates attached on the surface of polycrystalline TiO2 nanotubes were first prepared by electrospinning. In application to nonenzymatic glucose determination, the precusor was electrospun onto fluorine-doped tin oxide (FTO) glass directly. After hot press and calcination, a three-dimensional porous CuO/TiO2 modified electrode was fabricated. Because of the combination of hierarchical composite and three-dimensional structure, it exhibits a high sensitivity of 1321 渭A mM鈭?#xA0;1 cm鈭?#xA0;2 in the range from 10 渭M to 2 mM, a detection limit of 390 nM (S/N = 3) and a good stability.
