“…Metal NPs have intrinsic uncommon thermal, optical, physical, and chemical properties with a wide range of technological applications. [1][2][3][4] Among the metal NPs intensively studied, we can mention the noble NPs such as silver (Ag-NPs) 3 and gold (Au-NPs) 4 NPs; the metal oxide NPs such as zinc oxide, 5 copper oxide, 6 iron oxide, 7 magnesium oxide, 8 and titanium dioxide 9 NPs; and the halide NPs such as silver chloride (AgCl), 10 silver bromide, [11][12][13] and silver iodide 14,15 NPs. The innumerous crystal phase-controlled syntheses of metal NPs may include toxic chemicals and harsh reducing agents, which, after adsorbing on the surface of the NPs, may result in adverse effects on their applications.…”
