摘要：

Methanol steam reforming was investigated over novel Pd/In(2)O(3)/Al(2)O(3) and Pt/In(2)O(3)/Al(2)O(3) catalysts coated into microchannels. The investigations revealed, that Pt is much more active at still moderate CO selectivity compared to Pd. An In(2)O(3) content of 25 - 30 wt.% was required to minimize the CO selectivity of the Pt-containing samples. At a Pt/In ratio of 0.6, the catalyst with the highest Pt content of 15 wt.% showed also highest activity. Switching to conditions of oxidative steam reforming further increased the activity of the catalysts.
