Abstract Flowers, trees and coral like TiO2 films are first produced by the micro−arc-oxidation method in electrolyte of phosphate. Nanowhiskers with high surface area grow at the tail ends of the coralloid film when the positive current density is set to be 17.14 A/dm2. With acetamide in electrolyte, N element is doped. The analysis results indicate that the ratio of anatase phase to rutile phases is about 2:1 in the micro−arc-oxidation produced N-TiO2 film. The optical absorption edge red shifts in the presence of N doping.
