| 英文摘要 | uv raman spectroscopy is becoming a powerful technique for catalysis as well as many other fields such as chemistry, physics, biology, and material science mainly because it can avoid the fluorescence interference occurring in visible raman spectra and concurrently enhance the raman signal owing to the short wavelength and resonance raman effect. this article reviews the recent advances in catalytic characterization using uv raman spectroscopy, including the characterization of highly dispersed transition metal oxides on supports, transition metal ions in the framework of microporous and mesoporous materials, the synthesis mechanism of zeolites, and the surface phase of metal oxide catalysts. one of the advances is the successful identification of highly isolated transition metal ions incorporated in the framework of microporous and mesoporous materials such as ts-1, ti-mcm-41, fe-zsm-5, fe-sba-15, and v-mcm-41 base on the uv resonance raman effect. moreover, in an effort to gain a greater understanding of the formation mechanism of zeolites, we have recently developed an apparatus capable of studying hydrothermal reactions in situ uv raman spectroscopy by taking the advantage of uv raman spectroscopy. the synthesis mechanism of microporous materials (such as zeolite x and fe-zsm-5) has been investigated, which can sensitively detect the precursors and intermediates evolved in the synthesis solution and gels. in addition, the active sites and the structure of fe-zsm-5 with highly dispersed transition metal oxides on zeolite supports have been studied through resonance raman spectroscopy. the results demonstrated that the active oxygen species have been identified as the peroxide bridged di-nuclear iron species, and the reaction intermediates bear a degree of resemblance to the iron complex in soluble methane monooxygenase (smmo). another finding by uv raman spectroscopy is that the phase transformation in the surface region of most metal oxide nanoparticles (such as zro2 and tio2) is remarkably different from that in their bulk. this finding is extremely important to catalysis because the catalytic performance is generally dependent on the surface phase. for example, uv raman spectroscopic study clearly demonstrates that the generation of surface-phase junction on tio2 catalyst can significantly enhance the photocatalytic activity for hydrogen production. |
