1. A method of preparing an immobilized selenium body comprising:
(a) forming a mixture comprising selenium and a self-templated porous carbon;
(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,
wherein the self-templated porous carbon is made by a process that includes:
carbonizing a salt by melting until oversaturation of anions in the melt forms a crystallized salt in the melt;
increasing the viscosity of the melt until the melt coats surfaces of crystallites of the crystallized salt; and
solidifying carbon in the melt on the surfaces of the crystallites.
