Nanometer‐sized particles that are synthesized from the metal either by constructive or destructive routes are metal‐based NMs. Most of the metals can be synthesized in form of NMs (Salavati‐Niasari, Davar, & Mir, 2008); however, the most extensively studied metal‐based NMs include cadmium, aluminum, silver (Kim et al., 2007), iron, gold (Sun & Xia, 2002), copper (Ramyadevi et al., 2012; Ruparelia et al., 2008), and lead‐based NMs. The size of these materials varies from 10 to 100 nm with high surface area‐to‐volume ratio, unique surface charge, and pore size. Further, they can be either amorphous or crystalline, which can exist in different sizes and shapes such as spheres, and cylinders.
