A humic acid-derived foam consisting of a plurality of pores and pore walls, wherein the pore walls contain monolayer or few-layer humic acid-derived planes or sheets of hexagonal carbon atoms, the few-layer planes of hexagonal carbon atoms Or the sheet has 2-10 layers of stacked hexagonal carbon atomic planes with an interplanar spacing d from 0.3354 nm to 0.40 nm as measured by X-ray diffraction? 002#191, and wherein the monolayer or few-layer hexagonal carbon atomic plane contains 0.01% to 25% by weight of non-carbon elements, and wherein the humic acid is selected from oxidized humic acid, reduced humic acid , fluorinated humic acid, chlorinated humic acid, brominated humic acid, iodinated humic acid, hydrogenated humic acid, nitrided humic acid, doped humic acid, chemical Functionalized humic acid, or a combination thereof. |
