Photochemically controlled synthesis of anisotropic Au nanostructures : platelet-like Au nanorods and six-star Au nanoparticles
We report the shape-controlled synthesis of anisotropic Au nanostructures through TiO2-assisted photochemical reduction of HAuCl4. By using this method, we have successfully synthesized the platelet-like Au nanorods and six-star Au nanoparticles. Importantly, the platelet Au nanorod exhibits the uni...
