发展了一种简便的溶剂热法，通过将原位聚合的富N树脂在原位形成的胶体二氧化硅堆积区域内共凝胶化，合成了掺氮的3D双连续大孔/介孔碳。合成的材料具有丰富的吡啶/石墨氮，可观的比表面积和光滑的孔道(具有开放的中孔的相互连接的大孔)。16(Nm)。由于以上特点的综合作用，它表现出高的氧还原催化活性和优异的耐久性和耐甲醇渗透效应。
A facile solvothermal method is developed to synthesize N-doped 3D bicontinuous macro/mesoporous carbon through co-gelation ofin-situpolymerized N-enriched resin together within-situformed colloidal silica packing domains. The resultant material possesses abundant pyridinic/graphitic N, respectable surface area, and smooth pore channels (interconnected macropores with open mesoporesca. 16 nm). Due to the combined contributions of above features, it shows high oxygen reduction catalytic activity with excellent durability and tolerance to methanol crossover effect.
