Abstract  

N-doped TiO2 was prepared by the quick polymerization of Tetrabutyltitanate and phenolic resin with solvent thermal reactions using tetrabutyltitanate, phenolic resin, absolute ethanol, acetic acid, guanidine hydrochloride (GHC) and P123. The N- doped TiO2 was characterized by XRD, SEM, TEM, XPS, N2 adsorption-desorption and UV-Vis. We also investigated the effect of GHC adding amount to the photocatalytic activity by taking 4- aminobenzenesulfonic acid as a model test. The results showed that the N-doped TiO2 was composed of anatase phase with a particle size about 13.7 nm and the aggregate about 100 nm. There were lots of mesoporous between the particles. The doping of N element resulted in a red shift of the absorption edge. The absorption of visible light and photocatalytic activity of N-doped TiO2 are promoted with the increase of the adding amount of nitrogen source.The result was consistent with the atom fraction in N-TiO2 measured by XPS.
