8057 862 NiMoO4 2.5 0.5 μm SEM The scanning electron microscopy (SEM) images of microflowers CoMoO4 and NiMoO4 are shown in Figures 1A and S1A, respectively. The as-prepared CoMoO4 exhibits uniform flower-like structures with a size of 4–5 μm, whereas NiMoO4 shows a relatively smooth surface with a small size of 2–3 μm. 368.8
