摘要：

A TiO2/NiO core/shell nanorod array film is prepared by the combination of hydrothermal and chemical-bath deposition. Compared to the NiO nanoflake film, the TiO2/NiO core/shell nanorod array exhibits better electrochromism with reversible color changes bewteen transparency and dark brown, shows larger optical modulation (83%), higher coloration efficiency (60.6 cm(2) C1-) and better cycling performance. The enhancement of electrochromic performances is attributed to the synergetic contribution from the single crystalline TiO2 nanorod core and the ultrathin NiO nanoflake shell, as well as the ordered array geometry, which can all offer direct electrical pathways for electrons and increase the electron transport rate.
