Zero waste, single step methods of fabrication of reduced graphene oxide decorated with gold nanoparticles

This paper reports a novel approach to the use of carbon, in form reduced graphene oxide, as reducing agent for Au(III) chloride complex ions. allows fabrication composite material [email protected]r single-step process. The reduction ions was performed using high pressure, 50 bar, and temperature, 250°C, reactor. average diameter obtained gold nanoparticles below 3 nm. advantage oxide is its surface area. accelerates reaction rate significantly. greenness sustainability process are assessed by green chemistry metrics circularity indicators recently applied first time nanomaterial synthesis. As key metrics, atom economy (AE) measures degree incorporation reactant atoms into final product case research presented scoring 99%.
