Fig. 1. The synthetic scheme and characterization of Mox-Ni0.85Se/MoSe2. (a) A schematic illustration for the synthesis of Mox-Ni0.85Se/MoSe2. Low (inset) and high magnification (b) SEM, and (c) HAADF-STEM images of Mox-Ni0.85Se/MoSe2. (d) Bright field STEM image and corresponding EDS elemental mapping of Mox-Ni0.85Se/MoSe2. (e)-(g) From left to right are experimental HAADF-STEM image, structure model (Blue: Mo atom; Green: Ni atom; Red: Se atom), and simulated HAADF-STEM image of the selected area in (c), respectively.
