| 英文摘要 | ag-hollandite nanofibers were synthesized by refluxing a mixture of agmno4 and mn(no3)(2) in nitrate acid solution at 373 k and used for ethanol selective oxidation. the x-ray diffraction pattern showed that the main crystalline phase was ag-hollandite, but a small amount of pyrolusite was also formed. the n-2 adsorption-desorption isotherms confirmed the presence of a microporous structure. field emission scanning electron microscopy and transmission electron microscopy showed that the lengths of the nanofibers were 0.5-4.0 mu m, and the diameters were 10 - 20 nm. the ag-hollandite nanofibers gave a promising catalytic performance for ethanol selective oxidation to acetaldehyde, with an ethanol conversion of 82% and acetaldehyde selectivity of 95% at 503 k for 120 h time-on-stream. |
