Abstract
The present invention relates to sorbents including carbon and nitrogen. In various embodiments, the sorbent can remove mercury from a mercury-containing gas that includes sulfur (VI) such as SOmore efficiently than other sorbents. The sorbent can include a graphene edge comprising an active site for mercury oxidation and a nitrogen layer structure including cationic nitrogen atoms, neutral nitrogen atoms, or a combination thereof proximate the active site.
