Abstract:
1. A method comprising: pre-treating a surface of a carbon paper configured to grow a carbon nano tube by a method comprising submerging the carbon paper into sulfuric acid to improve the wettability of the surface of the carbon paper; forming a catalyst metal over a surface of the pre-treated carbon paper; growing the carbon nano tube by flowing a vapor phase carbon source on the surface of the carbon paper supported with the catalyst metal and maintaining an a predetermined temperature range; removing the catalyst metal from the grown carbon nano tube and pre-treating the surface of the carbon nano tube; and forming a platinum-based catalyst by flowing a vapor phase platinum-based precursor on the carbon nano tube to form a platinum-based nano catalyst supported carbon nano tube electrode.
