摘要
Flowers,trees and coral like TiO_(2)Rlms 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/dm^(2).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-TiO_(2)film.The optical absorption edge red shifts in the presence of N doping.
