Ultrahigh surface area hierarchical porous carbons based on natural well-defined macropores in sisal fibers†
Abstract
Hierarchical porous carbon with ultrahigh surface area (i.e., 3350 m2 g−1) is prepared by utilizing the natural well-defined organization of pores present in sisal fibers as the substrate for constructing hierarchical macro–meso–microporous structure, which allows for rapid molecular diffusion and high pore utilization and thus leads to excellent organic vapour
