氫能源在未來被視為一種相當具有潛力的能源，因為它的能量密度高，且使用過程不會造成污染，而甲烷蒸氣重組仍然是工業上用來製造氫氣的方法，鎳觸媒應用在此反應時，雖然有價格低以及活性高的優勢，但是在高溫時會受到積碳以及燒結問題影響。本實驗室先前研究將鎳擔載於LaZrCeOX(LZC)螢石結構的金屬氧化物載體上，發現Ni/LZC觸媒可減少積碳、燒結現象，且具有良好活性，但結果顯示當鎳含量小於10 wt%時，Ni/LZC會因比表面積過低而失去活性。本研究在共沉澱法製備觸媒時加入油胺(oleylamine)，期望觸媒能與油胺形成的微胞一起沉澱，再藉由鍛燒程序將微胞移除，實驗結果顯示添加油胺後，觸媒的晶體結構並無顯著影響，載體與鎳的結晶大小皆為4-5 nm，但BET結果顯示觸媒的比表面積隨著油胺添加量增加而上升，添加0.1 M油胺的觸媒比表面積上升至99.9 m2/g，同時也觀察到有約10 nm的孔洞生成，TPD、TEM結果發現觸媒的顆粒堆疊現象減少、活性金屬的分散度也有增加，比較油胺添加對Ni/LaZrCeOx觸媒在甲烷蒸氣重組的測試中，結果顯示油胺並不會導致觸媒反應性的改變，並研究將5% Ni/LZC_OAm0.1應用於丙烷及甘油蒸氣重組也呈現出良好的斷C-C鍵能力在600°C時兩反應皆可達到完全轉化，於丙烷蒸氣重組時與27.9% Ni/LZC有相同的活化能與TOF，且與文獻相比時發現Ni/LZC有較低的活化能≈ 62 kJ/mol，但是仍有明顯積碳現象的發生，而Ni/LZC在甘油蒸氣重組時相對於文獻也有高CO2選擇率以及H2產率，對於將甘油轉化為氣相產物能力優異，且由於反應機制的差異造成以甘油做為蒸氣重組的反應物時相對丙烷，減少了產物中CH4的占比以及積碳的現象。

Hydrogen energy serves as potential energy in our future. The methane steam reforming reaction is still the industry's most used method for hydrogen production. The use of nickel catalysts is significant in this reaction due to their affordable cost and high reactivity. However, they tend to face a severe coking issue at high temperatures. In our research using Nickel loading on LaZrCeOX(LZC), LaZrCeOX is a mixed metal oxide support with a fluorite structure, we found that Ni/LZC has high thermal stability and coking resistance ability, Our laboratory has found that a Nickel loading of less than 10 wt% in the catalyst results in a decrease in activity due to a low specific surface area (<1 m2/g). This study aims to improve the 5% Ni/LZC reactivity on methane steam reforming by increasing the specific area. Using Co-Precipitation to prepare the catalyst, adding oleylamine during preparation. It is expected that the micelles formed by oleylamine can occupy space on the catalyst during precipitation and be removed by calcination. Using different concentrations of oleylamine to make the comparison. The BET result shows that the surface area of the catalyst increases with the additional amount of oleylamine. Also, in the BJH results 10 nm pores were formed. The TEM、H2-TPD and EXAFS results show that the catalyst with oleylamine addition reduced the stacking of catalyst particles and increase the dispersion of active metal. Activity tests show that 5% Ni/LZC_OAm0.1 has better reactivity and no serious coking tendency during methane steam reforming.
Apply 5% Ni/LZC_OAm0.1 to propane and glycerol steam reforming. We found that it shows a good ability to break carbon bonds in the structure of propane and glycerol both achieving 100% conversion at 600°C. In propane steam reforming, 5% Ni/LZC_OAm0.1 has the same activation energy and TOF as 27.9% Ni/LZC, also found that Ni/LZC has a lower activation energy than the literature reported. But it still has coking formation at 600°C. In glycerol steam reforming Ni/LZC also performs a good activity it has 100% glycerol conversion and a high H2 Yield at 600°C.
