1084CuMnFe-ATP5-10nmTEMThe specific surface area and pore-size distribution of CuMnFe-ATP were calculated based on nitrogen adsorption–desorption results. As Fig. 3C shows, the CuMnFe-ATP NPs exhibited a type IV isotherm, which possessed significant hysteresis at the range of 0.4–1.0 P/P0. The surface area was calculated as 37.31 m2 g− 1 , according to the Brunauer-EmmettTeller model. The large surface area may be induced by the collapse of the CuMnFe-ATP NP structures after drying in vacuum. From Fig. 3D, although the pore-size distribution of CuMnFe-ATP NPs was majorly in the range of 5–10 nm, some pore sizes were about 27.5 nm. The generation of larger pores suggests the collapse of the CuFeMn-ATP NPs. Also, the SEM micrograph indicates the existence of large pores in the CuMnFe-ATP NPs, which also proves the structure collapse.37.31
