調製に際しては、たとえば実施例1の場合にはSWNH 96mgにPtの量で8mgのPtアンミン(IV)溶液を加えて1時間攪拌した後、ろ過を行い10mLの純水で3回洗浄を行った。そののち、フィルター上に残った試料を窒素流通下で乾燥させ(室温)、Pt/SWNH触媒を得た。
比較例2:Eu/SWNH(Eu 0.1mmol/SWNH 1g当たりを担持)
比較例3:Ni/Al2O3(Ni 4wt%担持)
比較例4:Ru/Al2O3(Ru 4wt%担持)
これらの触媒を用いて、理論水素SV=1250hr-1、水蒸気メタン比3.5の条件下にメタン水蒸気改質反応を行った。なお、測定装置にはアジエント社のマイクロガスクロを使用した。
