| 英文摘要 | microporous vanadosilicates with octahedral vo6 and tetrahedral sio4 units, better known as am-6, have been hydrothermally synthesized with different morphologies by controlling the na/k molar ratio of the initial gel mixtures. the morphology of the am-6 materials changed from bulky cube to nanofiber aggregates as the na/k molar ratio decreased from 1.9 to 0.2. raman spectroscopy revealed that the vo3- intermediate species plays an important role in the formation of the nanofiber morphology. the orientation of -v-o-v- chains in nanofiber aggregates was examined by confocal polarized micro-raman spectroscopy. it was found that these aggregates are assemblies of short -v-o-v- chains perpendicular to the axis of nanofibers. the obtained am-6 nanofibers greatly increase the exposed proportion of vo terminals, and thus improve the catalytic performance. |
