Abstract
An immobilized chalcogen system or body includes a mixture or combination of chalcogen and carbon. The carbon can be in the form of a carbon skeleton. The chalcogen can include oxygen, sulfur, selenium, or tellurium, or a combination of any two or more of oxygen, sulfur, selenium, and tellurium. The activation energy for chalcogen to escape the immobilized chalcogen system or body is ≥96 kJ/mole.
