Abstract

In a method of preparing an immobilized selenium system or body, a selenium - carbon - oxygen mixture is formed. The mixture is then heated to a temperature above the melting temperature of selenium and the heated mixture is then cooled to ambient or room temperature, thereby forming the immobilized selenium system or body.

Claims (11)

The Invention Claimed Is:
1. A method of preparing an immobilized selenium body comprising: (a) forming a mixture of selenium, carbon, and oxygen; (b) heating the mixture of step (a) to a temperature above the melting temperature of selenium, ; and (c) causing the heated mixture of step (b) to cool to ambient or room temperature, thereby forming the immobilized selenium body.
2. The method of claim 1, wherein the carbon is one of a self-templated carbon or a foreign- templated carbon.
3. The method of claim 1, wherein, for selenium loading in the carbon of < 50%, the amount of oxygen in the mixture is ³ 0.63 milli-mole/gram.
4. The method of claim 1, wherein, for selenium loading in the carbon between 50% (exclusive) and 60% (inclusive) (i.e., 50% < selenium loading < 60%), the amount of oxygen in the mixture is ³ 0.5 milli-mole/gram.
5. The method of claim 1, wherein, for selenium loading in the carbon of ³ 60%, the amount of oxygen in the mixture is ³ 0.31 milli-mole/gram.
6. The method of claim 1, further including, prior to step (a), activating the carbon thereby forming pores in the carbon.
7. The method of claim 5, further including, combining or mixing the activated carbon with an oxidizing agent
8. The method of claim 7, wherein the oxidizing agent comprises at least one of the following: nitric acid; hydrogen peroxide; organic peroxide; oxygen; and/or ozone.
9. The method of claim 7, wherein the oxidizing agent comprises at least one of the following in an aqueous environment: ammonium persulfate; sodium persulfate; potassium persulfate; a salt of manganese; a salt of vanadium, and/or a salt of chromium.
10. The method of claim 1, wherein the self-templated carbon is made by a process that includes: carbonizing a salt by melting until oversaturation of anions in the melt forms a crystalized salt in the melt; increasing the viscosity of the melt until the melt coats surfaces of crystallites of the crystalized salt; and solidifying carbon in the melt on the surfaces of the crystallites.
11. An immobilized selenium body comprising a mixture of: selenium; carbon; and oxygen.
