“…Besides their intrinsic enzymatic activity, CNMs and their derivatives can be also utilized as modulators to further improve the catalytic activity and stability of artificial peroxidase. Many classic artificial peroxidases, for instance, metal oxides (for example, Fe 3 O 4 , FeO x H, Fe 2 O 3 , Co 3 O 4 , ZnO, CuO, Cu 2 O, CeO 2 , CoFe 2 O 4 , and WO 3 ), metal hydroxide, metal chalcogenides (for example, CoSe 2 , CuS, and MoS 2 ), metal nanoparticles (for example, Pt, Pd, Au, Ag, and Fe), metal alloys (for example, PtPd, PdNi, AuPd, AuAg, CuAg, and FeCo), metal ions (for example, Cu 2+[152] ), complexes (for example, hemin, chiral metallo‐supramolecular complex, Fe‐phenanthroline, and prussian blue…”
