The application of metal precursors depends on the desired nanomaterial and the synthesis method. For instance:
Synthesis of Nanoparticles: Metal salts are often reduced in solution to form metal nanoparticles. For example, gold nanoparticles can be synthesized by reducing gold chloride with sodium citrate. Formation of Thin Films: Organometallic compounds are decomposed in CVD processes to form thin metal films on substrates. For example, tungsten hexacarbonyl can be used to deposit tungsten films. Creation of Nanowires: Metal alkoxides can be used in sol-gel processes to form nanowires. For example, silicon nanowires can be synthesized using silicon tetrachloride as a precursor.
