Abstract
Briefly described, compositions, materials including the compositions, methods of using the compositions, and methods of degrading contaminants, are described herein. The composition can include a polyoxometalate/ cationic silica material. In addition, the compositions can be made of a polyoxometalate/cationic silica material, a copper (II) salt having a weakly bound anion, and a nitrate salts. Further, the compositions can be made of a polyoxometalate/cationic silica material, a copper (II) salt having a weakly bound anion, a compound selected from tetraethylammonium (TEA) nitrate, tetra-n-butylammonium (TBA) nitrate, and combinations thereof.
