One Step Synthesis of High Surface Area Hierarchically Structured Monolithic Porous Carbons Doped with Nanosized Zinc Oxide

摘要

￡oHigh surface area hierarchically structured monolithic porous carbons doped with nanosized zinc oxide were prepared through polymerization of resorcinol with formaldehyde catalyzed by zinc acetate, followed by subcritical drying under ambient pressure and carbonization. During the carbonization process, zinc acetate converted into zinc oxide. The maximal up to 25% in weight of zinc oxide can be homogeneously doped into the structure of monolithic porous carbon. The BET surface area of the obtained zinc oxide doped porous carbon can be as high as up to 688 m 2 /g, and total pore volume up to 2.30 cm 3 /g. By changing the reaction parameters, the textural parameters of porous carbon and the size of zinc oxide nanoparticles can be adjusted.
