以苯酚和甲醛为碳前驱体，在硫酸存在下，以可去除的胶体二氧化硅晶体为模板，通过碳化反应合成了均匀有序的多孔碳骨架。这些高度有序的均匀多孔碳作为催化剂载体时，导致在燃料电池中的甲醇氧化的催化活性大大提高，可能是由于其三维互连的均匀孔结构和高的比表面积。
Ordered uniform porous carbon frameworks were synthesized against removable colloidal silica crystalline templates by carbonization of phenol and formaldehyde as a carbon precursor in the presence of sulfuric acid. These highly ordered uniform porous carbons when used as a catalyst support, resulted in much improved catalytic activity for methanol oxidation in fuel cell probably due to their three-dimensionally interconnected uniform pore structures and high surface areas.
