7896 679 R-MnCo2O4 nm TEM Figure 1a,c shows the typical TEM images of the MnCo2O4 and R-MnCo2O4 nanotubes, respectively. Furthermore, three characteristic d-spacing values of approximately 0.25, 0.30, and 0.48 nm are observed in the HRTEM images of the MnCo2O4 nanotubes, which can be ascribed to the (311), (220), and (111) planes, respectively (Figure 1b).

Furthermore, the R-MnCo2O4 nanotubes showed a favorable oxidase-like activity toward oxidation with the aid of molecular oxygen.
