摘要：

The methanol decomposition to carbon monoxide and hydrogen is catalyzed at 250 degrees C over nickel-silica composites prepared by the sol-gel method while the activity is increased with increase in the content of nickel up to 40 wt%. The activity of nickel supported on silica prepared by the conventional impregnation technique is also increased with the nickel content but almost reaches a plateau at the nickel content of 10 wt%. The maximum activity found with the former is significantly higher than that with the latter.
