摘要
近些年来,有序多孔碳材料由于在吸附,催化和电化学等方面性能优良,使其成为了一个研究热点。在这项工作中,利用生物质原料作为碳源/氮源,嵌段共聚物P123作为软模板,通过模板固定剂将模板固定,水热之后得到有序碳材料前驱体。通过进一步除掉模板剂和模板固定剂,得到有序介孔碳材料。体现了绿色化学和环境友好型化学的理念。我们通过使用不同的糖做碳源(如:葡萄糖,蔗糖等),都得到了有序介孔碳材料,证明了这种方法的普适性。我们还通过扫描电子显微镜、透射电子显微镜和氮气吸脱附测量对这种多孔材料的结构和物理性质进行了详细的研究。这种多孔材料拥有较大的比表面积(from 330 to 620 m~2g~(-1)at 77 K)和较高的孔容(from 0.35 to 0.72 cm~3g~(-1))。
Recent years, synthesis of porous ordered hydrothermal carbon has been a research hotspot for its better performance in adsorption, catalysis or electrochemistry. In this work, we proposed a method to synthesize porous ordered hydrothermal carbon materials by using soft-templating method. Different biomass derivatives were employed in this work to verify the universality of the synthesis method. The obtained materials have relatively large BET surface area(from 330 to 620 m~2 g~(-1) at 77 K) and pore volume(from 0.35 to 0.72 cm~3 g~(-1)).
