| 英文摘要 | Monodispersed tungstic acid nanoparticles with an average diameter of 20 nm were prepared by a ultraviolet light irradiation of oxotungsten-citrate complex aqueous solution. the results of ir spectroscopy show that oxotungsten-citrate complex firstly decomposes into citric acid and tungstic acid under uv-irradiation and then citric acid undergoes photo-degradation under the catalysis of tungstic acid. xrd results indicate that the obtained product consists of wo3 center dot 2h(2)o and wo3 center dot h2o. the irradiation time and molar ratio of citric acid to sodium tungstate (n(cit)/n(st)) have important effect on the product composition. prolonging the irradiation time, the content of wo3 center dot 2h(2)o in the product decreases while that of wo3 center dot h2o increases, and the particle size of the product increases and the size distribution widens. increasing n(cit)/n(st), the content of wo3 center dot 2h(2)o in the product increases while that of wo3 center dot 2h(2)o declines, furthermore, the particle size of the product decreases and the size distribution becomes narrower. |
