Plasma-induced non-equilibrium liquid chemistry is used to synthesize gold nanoparticles (AuNPs) without using any reducing or capping agents, since the development of new high technologies to obtain nanoscale inorganic compounds is currently relevant. The morphology and optical properties of the synthesized AuNPs are characterized by transmission electron microscopy (TEM) and ultraviolet–visible spectroscopy. The UV–vis spectroscopy revealed the formation of gold nanoparticles by exhibiting surface plasmon absorption maxima at 548 nm. Plasma processing parameters affect the particle shape and size and the rate of the AuNP synthesis process. Transmission electron micrograph (TEM) showed presence of spherical particles in the range of 7–60 nm size. Particles of different shapes (e.g. spherical, triangular,) are synthesized in aqueous solutions. Conclude that H2O2 plays the role of the reducing agent which converts AuCl ions to Au0 atoms, leading to nucleation growth of the AuNPs.
