Preparation, Adsorption Properties and Microwave-Assisted Regeneration of Porous C/SiC Ceramics with a Hierarchical Structure
Source abstract
Abstract
Porous C/SiC ceramics were prepared by chemical vapor reaction of SiO and porous C/C composites. The porous C/SiC ceramics presented a hierarchical structured consisted of carbon fibers, SiC layer, microspheres and nanowires. The density of porous C/C composites control the growth of SiC nanowires and nanolayer, and influence the pore size distribution and specific surface area of the porous C/SiC ceramics. The C/SiC samples converting from the C/C composites with a density of 0.46 g/cm3 possess the superior adsorption properties. The adsorption efficiency can reach 98.2% within 80 min, indicating that C/SiC samples have a promising adsorption property for MB from aqueous solution. Furthermore, the adsorption efficiency after five cycles microwave regeneration still reached 80.2%, which present excellent regeneration stability.
