Classification: CPC B  C | IPC B  C

Claim 0:
1. A method of manufacturing a sorbent material, the method comprising:
providing a carbonaceous material;
activating the carbonaceous material to form a precursor activated carbon;
doping the precursor activated carbon by contacting the precursor activated carbon with a copper source and a nitrogen source to thereby form a doped precursor activated carbon;
wherein the copper source comprises copper sulfate pentahydrate, CuSO4·5H2O, or copper (II) carbonate hydroxide, CuCO3(OH)2, and the nitrogen source comprises one or more of urea, CO(NH2)2, ammonium carbonate, (NH4)2CO3, or aqueous ammonium hydroxide, NH4OH (nominally aq, 28 wt. %);
calcining the doped precursor activated carbon in a calcining atmosphere that does not cause any substantial oxidation or activation of the doped precursor activated carbon to thereby form a sorbent material.
