| 英文摘要 | The influence of calcination temperature on the structure and catalytic behavior of ni/tio(2)-sio(2) catalyst, for co(2) reforming of methane to synthesis gas under atmospheric pressure, was investigated. the results showed-that the ni/tio(2) sio(2) catalyst calcined at 700 degrees c had high and stable activity while the catalysts calcined at 550 and 850 degrees c had low and unstable activity. depending on the calcination temperature, one, two, or three of the following ni-containing species, nio, ni(2.44)ti(0.72)si(0.07)o(4), and nitio(3) were identified by combining the temperature programmed reduction (tpr) and x-ray diffraction (xrd) results. their reducibility decreased in the sequence: nio>ni(2.44)ti(0.72)si(0.07)o(4)>nitio(3). it suggests that high and stable activities observed over the ni/tio(2)-sio(2) catalyst calcined at 700 degrees c were induced by the formation of ni(2.447)ti(0.72)si(0.07)o(4) and smaller nio species crystallite size. |
