Abstract

High-energy ball milled nanocrystalline TiO₂ (anatase) was analyzed by means of electrochemical impedance spectroscopy in a temperature range from 473 K to 873 K and under reducing and oxidizing atmospheres. The electrical properties are compared with the photocatalytic activity of the samples.
