以柠檬酸（CA）和磷酸铝（AIPO）为原料，采用碳化法制备了多孔炭材料。所得炭材料具有中孔和/或微孔的特征，具有均匀的孔径分布和一定程度的石墨化相特征。通过在CA/AIPO复合材料中加入适量的蔗糖（SU），可以在一定范围内进一步调节材料的结构参数，包括平均孔径、孔体积和比表面积。在碳化过程中原位生成的介孔结构AIPC可以作为制备多孔炭材料的硬模板。我们认为CA的均匀分布以及CA与磷酸铝之间存在合适的相互作用是形成介孔碳网络的关键因素。(C)2008年爱思唯尔公司All rights reserved.
A simple and efficient route is reported for the synthesis of porous carbon materials via carbonizing a kind of composite containing citric acid (CA) and aluminum phosphate (AIPO). The resulting carbon materials, bearing mesoporous and/or microporous characteristics, possess uniform pore size distribution and certain degree graphitic phase characteristic. The structural parameters of these materials, including mean pore sizes, pore volumes and specific surface areas, can be further tuned within a certain range by addition of suitable amount of sucrose (SU) into the CA/AIPO composite. The mesostructured AIPC, which is formed in situ during the carbonization, can be regarded as a hard-template for the formation of porous carbon material. We propose that the uniform distribution of CA, and the presence of suitable interaction between CA and aluminum phosphate are critical factors for the formation of mesoporous carbon network.
