Abstract

The relation among the change of the crystal structure, the amount of doped N and the photocatalytic activity for the decomposition of methylene blue was studied. The N-doping was promoted by the change of the crystal structure from the rutile phase to the anatase phase. The photocatalytic activity for the decomposition of methylene blue was enhanced by an increase in the amount of anatase crystals and doped N.

 

Keywords: Laser ablation; N-doping process; Crystal change; N-doped TiO2 thin film; Dye decomposition.
