Robust nanozymes with high activities and multifunctional catalytic properties are highly sought by the sensing community as replacements for delicate natural enzymes. Herein, we report the discovery of a multifunctional nanozyme comprising Mn 3 Fe 2.7 C nanoparticles encapsulated by nitrogen-doped carbon shells embedded with carbon nanotubes (Mn 3 Fe 2.7 C@C (700) ), prepared by pyrolysis of a Prussian blue analogue (specifically KMnFe(CN) 6 ·2 H 2 O) at 700 °C in N 2 . Due to synergy between the Mn 3 Fe 2.7 C nanoparticles and the distinc...
