燃料電池中的白金需要支撐材料來獲得最高的表面積。擁有較高表面積的白金粒子有更高的機會與氫氣燃料或氧氣反應物反應。支撐材料需提供好的位點與白金粒子反應，為了使白金粒子有好的反應位點，氮參雜是其中一個努力的方向。通常，白金的支撐材料是碳材，但是非碳材支撐材料各自擁有許多特性，使得其研究十分有趣與充滿挑戰。在這份研究中，我利用水熱與氨氣熱處理製備了氮氧化鈦奈米薄片，鈦的原料、氮化溫度和與白金的載量比是這份研究的變量。我做了一些測試來確認氮氧化鈦的特性， X射線衍射（XRD）是用來確認材料中形成的晶體結構，掃描電子顯微鏡（SEM）和 穿透式電子顯微鏡（TEM）是用來觀察晶體的結構與形態，電化學測試則可以得到材料的電化學性能。鈦的原料是硫酸氧鈦(TiOSO4)時，觸媒可以獲得最好電化學性能，同時在氮化溫度900o C與10%載量比時，觸媒分別都可以獲得相同條件下最好的性能。

Platinum in fuel cell need a support material to get highest surface area. With high surface area the platinum particle has high chance to react with hydrogen fuel or oxygen reactant. Support materials need to provide a good site to interact with platinum particle, nitrogen doping on surface of support material is one of efforts to make a good site for platinum particle. In this study, titanium oxynitride nanoflake synthesize was carried out by hydrothermal and heat treatment in NH3 gas. Titanium source, nitriding temperature and loading ratio of platinum became a study variable. Titanyl sulfate (TiOSO4) is a source of titanium which have better a better electrocatalyst activity compare to TiO2 as a titanium precursor. While the variation at 900o C of the nitriding temperature and 10 wt% loading ratios have the highest activity.
