1. A method of preparing an immobilized selenium body comprising:
(a) forming a porous foreign-templated carbon using a process comprising:
preparing a liquid solution comprising a carbon-source precursor and salt template particles;
freezing the liquid solution to form a solid mixture;
carbonizing the solid mixture to form a carbonized mixture comprising the porous foreign-templated carbon, the porous foreign-templated carbon having oxygen species therein and comprising micropores, mesopores and macropores, where 50 to 99% of the pores of the porous foreign-templated carbon are microporous; and
washing, filtering, and drying the carbonized mixture to obtain the porous foreign-templated carbon;

(b) forming a mixture of selenium and the porous foreign-templated carbon;
(c) heating the mixture of step (b) to a temperature above the melting temperature of selenium; and
(d) cooling the heated mixture of step (c) to ambient or room temperature to form the immobilized selenium body.
