METHOD OF MAKING CARBIDE DERIVED CARBON WITH ENHANCED POROSITY AND HIGHER PURITY

摘要

Purity (chemical composition) and porosity of carbons are important for most of their applications. There are several methods of making porous carbons. Carbide derived carbon represents a method of manufacturing carbon from metal carbides by thermochemical etching of metals and/or metalloids at elevated temperatures. This invention provides a method of manufacturing carbide derived carbon with higher purity. The produced carbons can be used in several applications where higher purity carbons are desired including but not limited to gas chromatography, liquid chromatography, supercapacitors, batteries, fuel cells, hemodiafiltration, enterosorbent, and toxin removal from biological fluids.
