a Schematic illustration of the hydrothermal synthesis of M-CoSe2-DETA. The balls in purple, green and pink represent Co, Se, and dopants, respectively. b STEM elemental mapping images of M-CoSe2-DETA nanobelts. Scale bars, 100 nm. c, d R-space curve-fitting of EXAFS spectra (c) and corresponding Re(k3χ(k)) oscillations (d) of Pb-, Cr-, Mn-, Fe-, Zn- and Mo- CoSe2-DETA samples.
