催化劑一般由金屬與金屬氧化物組成，金屬氧化物有助於催化劑行氧化還原反應，每種支撐物都有不同的性質，也使得金屬和支撐物的搭配有更多的選擇。催化劑在金屬上的研究已經很豐富，故以不同的支撐物為主要研究方向。
在支撐物的選擇上使用了螢石結構(CeO2)和鈣鈦礦結構(BZO)作為支撐物，螢石結構(CeO2)之支撐物有氧空穴能提供以增進氧在金屬表面的流動性；鈣鈦礦結構(BZO)支撐物除了有助於抑制碳沉積和金屬燒結具有良好的熱穩定性之外，且可以有效的利用水，促使催化劑效能提升。金屬方面選用Ruthenium和Rhodium這2種有助於C-C鍵斷裂並有著最高氫氣產率反應效果較好的金屬。
在不同外在條件下，如不同氧氣量的條件因支撐物都能有效利用環境中的氧氣、不同的水/乙醇混合比例因鈣鈦礦結構(BZO)支撐物能夠另外的利用環境中的水提升催化劑的效能，來進行實驗。這些使我們能瞭解在乙醇蒸氣重組反應中，不同催化劑的性能以及它們對反應的影響。可以在乙醇比例改變上看到水在乙醇蒸氣重組反應的影響力，而增加氧氣含量可以有效的提升乙醇轉換效率和氫氣產率。
Catalyst is generally composed of a metal and metal oxide. Metal oxide contribute to a redox reaction catalyst. Each support has different properties,that let collocation of metal and support are more choice. Catalysts research have been very rich on the metal. Therefore, support is the main research directions.
We select fluorite structure (CeO2¬) and perovskite(BaZrO3) as support. Fluorite structure support can inhibition of carbon deoisition,and it has oxygen vacancy, that can enhance mobility of oxygen in the metal surface. Perovskite structure can inhibition of carbon deoisition, and it can effectively use the water promote catalyst performance improvement.
In the effect of catalytic condition, higher ratios O2 and H2O to ethanol can engance the hydrogen production, attributable to that these oxidants can help for the ethanol based of C-C bond cleavage on the side product. Especially perovskite show the batter sensitivity, indicating that water use an more important role.
