| 英文摘要 | fealpo4-5 samples with various iron contents were investigated by uv resonance raman spectroscopy and uv-vis spectroscopy. the raman spectra of fealpo4-5 show four feature bands related to the framework iron at 630, 1060, 1140, and 1210 cm(-1) when excited by 266 nm laser. it is found that only part of ferric ions could enter into the framework, while the others exist in the extra-framework in the form of six-coordinated state. this kind of iron gives characteristic raman band at 285 cm(-1). combined with uv resonance raman spectroscopy, uv-vis spectroscopy, and x-ray diffraction, the crystallization process of fealpo4-5 (al/fe = 760) was studied. it is found that, in the early stages of the crystallization, the iron species exist in the form of six-coordinated state while attached to the end of the 1-dimensional alpo4 chain. the fe-o bonds in the six-coordinated state hamper the crystallization of alpo4. the crystallization of the fealpo4-5 began when the reaction between the 1-dimensional alpo4 chains occurred. at the same time, the six-coordinated ferric ions converted to the tetrahedral iron. |
