Abstract
The invention provides a sorbent material comprising a PSA that is synthesized via a sol-gel process. The sorbent material enables higher loading of PSA and other functional groups than conventional sorbents. The sorbent material can further encapsulate carbonaceous and/or non-carbonaceous particles that are distributed throughout the sorbent network. The invention also relates to a method of making the sorbent materials.
