Mentions: Figure 2A–C displays the scanning electron microscopy (SEM) images of the as-synthesized NiWO4 material, which revealed the octahedron-like morphology with an average crystalline size of ca. 2.0 ± 0.1 μm. Further analysis by energy dispersive X-ray (EDX; Fig. 2E) confirmed the presences of anticipated elements, namely oxygen (O), nickel (Ni), and tungsten (W) with a concentration of ca. 25, 5 and 70 wt%, respectively (Fig. 2D). Moreover, the X-ray diffraction pattern (XRD) profile of the as-prepared NiWO4 in Fig. 2F shows diffraction peaks accountable for the (010), (110), (011), (111), (002), (200) planes, and so on, which match with that of crystalline NiWO4 (JCPDS file no. 15-0755)2829.
