Claim 21:
22. A method of preparing an immobilized selenium body comprising:
(a) forming a mixture of selenium and a 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;
(b) heating the mixture of step (a) to a temperature above the melting temperature of selenium; and
(c) cooling the heated mixture of step (b) to ambient or room temperature to form the immobilized selenium body, wherein
for a selenium loading in the immobilized selenium body of ≤50% by weight, the amount of oxygen species in the immobilized selenium body is ≥0.63 mmol/g,
for a selenium loading in the immobilized selenium body between >50% and ≤60% by weight, the amount of oxygen species in the immobilized selenium body is ≥0.5 mmol/g, and
for a selenium loading in the immobilized selenium body of ≥60% by weight, the amount of oxygen species in the immobilized selenium body is ≥0.31 mmol/g.
