采用模块化的概念研究了碳基催化剂的制备。应用模板辅助路线以获得表现出不同分数的石墨物种的催化剂，同时保留它们的中孔性。采用低温氮气吸附、粉末X射线衍射、热重分析、X射线光电子能谱、透射电子显微镜和拉曼光谱等手段对炭材料进行了表征。将合成的复型催化剂用于双氧水氧化脱氢和电化学氧还原反应。讨论了不同碳物种，即无定形碳、小石墨微晶和大石墨微晶在催化行为中的作用。图形摘要
AbstractThe preparation of carbon based catalysts following a modular concept has been investigated. A template assisted route was applied to obtain catalysts exhibiting different fractions of graphitic species while retaining their mesoporosity. The carbon materials were characterized by means of low temperature nitrogen adsorption, powder X-ray diffraction, thermogravimetry, X-ray photoelectron spectroscopy, transmission electron microscopy, and Raman spectroscopy. The synthesized replicas were tested as catalysts in oxidative dehydrogenation of ethylbenzene and electrochemical oxygen reduction reaction. The role of the different carbon species, namely amorphous carbon, small graphitic crystallites, and large graphitic crystallites in the catalytic behavior was discussed.Graphical Abstract
