POROUS COMPOSITE PARTICULATE MATERIALS, METHODS OF MAKING AND USING SAME, AND RELATED APPARATUSES

摘要

In an embodiment, a porous composite particulate material includes a plurality of composite particles. Each composite particle includes an acid-base-resistant core particle at least partially surrounded by one or more layers of acid-base-resistant shell particles. The shell particles are adhered to the core particle by a polymeric layer. The shell particles and/or core particles may be made from an acid-base-resistant material that is stable in harsh chemical conditions. For example, the shell particles may be made from diamond, graphitic carbon, silicon carbide, boron nitride, tungsten carbide, niobium carbide, zirconia, noble metals, combinations of the foregoing, or other acid-base-resistant materials and the core particle may include at least one exterior layer of non-diamond carbon. The porous composite particulate materials disclosed herein and related methods and devices may be used in separation technologies, including, but not limited to, chromatography and solid phase extraction.
