“…A variety of possible photo-sensitive nano-semiconductor metal halide/oxides/sulphide, such as TiO2, ZnO, CuO, BiFeO3 and Carbon-based nanostructures have been produced and employed as photocatalysts for water purification, thanks to rapid advances in nanotechnology [11]. This innovative interdisciplinary branch of science and technology leads to the formation of different morphologies like nanoparticles [12-16][17], nanotubes [18,19], nanorods [20,21], nanocubes [22] and nanosheets [23] by using numerous advanced methods such as hydrothermal, solvothermal, sol-gel, microwave, co-precipitation methods [24] with different applications in many fields such as from basic chemistry [25][26][27][28], physics [29][30][31] to the advanced electronics [32][33][34][35][36], nanotechnology [37][38][39][40][41], biotechnology [42][43][44][45][46][47] by altering the properties like mechanical [17,48] physical [49][50][51] and magnetic [52,53] so they come up with an ideal of environmental friendly [54], with a motto of decreasing the pollutions [55,…”
