SEM images of CoS2 particles a without GO, b with 1 mg/mL GO, and c with 2.3 mg/mL GO. d Low magnification TEM image of CoS2/rGO with 2.3 mg/mL GO. e An enlarged TEM image of CoS2/rGO and f a high resolution TEM image of CoS2, the latter showing d-spacing of 0.27 nm in the (200) plane. The inset in f provides a diffraction pattern of the CoS2 in the white square
