A new TiO2/Mg(OH)2 multifunctional composite material was prepared by ammonia bubbling process.Nitrogen and iron codoped TiO2 powder were obtained by the hydrothermal method using titanium tetrabutoxide as precursor and ammonium nitrate and Iron(Ⅲ) nitrate nonahydrate as nitrogen and iron source.The composite material was characterized by XRD,FE-SEM,FT-IR and TG.The results indicate that at 75 ℃,the particle size distribute uniformly(D50=0.69 μm) with ammonia feeding time for 1h.SEM analysis shows that the flake-like hexagonal product is of good dispersibility.XRD analysis indicates that it's I(001)/I(101)=0.71.TG-DTA analysis indicates that the water loss was 24.9% of the total weight between 322 ℃ and 396 ℃ with the highest endothermic temperature at 376.2 ℃.The quality of samples could satisfy the demand of flame retardants.The photodegradation rate of the Rhodamine b is 56.3%.
