Reaction–Diffusion Assisted Synthesis of Gold Nanoparticles: Route from the Spherical Nano-Sized Particles to Micrometer-Sized Plates

The design of nanoparticles desired sizes and shapes 2D nanostructured materials is challenging important due to their unique physical chemical properties. One the most common methods for generation metal wet synthetic route in which ions are reduced formed particles stabilized liquid phase. Here we show a facile powerful method synthesize gold solid agarose gel utilizing diffusion reagents using Turkevich at room temperature. Our technique yields spatially separated by (spheres plates) column. We have achieved 4 orders magnitude difference synthesized with linearly increasing trend function spatial position. also generated micrometer-sized nanoplates triangle, truncated or hexagon attaining almost length-to thickness ratio 500, representing magnificent power reaction–diffusion assisted synthesis.
