Silver Gold Synthesis

Microwave Aided Synthesis Of Silver And Gold

Here we reported the extremely simple one-pot synthesis of silver and gold nanoparticles in a rapid manner. Aqueous leaf extract of the most admired energy plant Jatropha curcas is used as reducing agent here. An alternate and safe energy source, house-hold microwave oven constituted the reaction chamber. Silver and gold nanoparticles were characterized by UV-visible, FT-IR, Powder XRD

Photochemical Synthesis Of Gold Nanorods

the role of silver or AgBr is to controlfacilitate the aggregation of the particles and then be phase-separated from the final gold nanorods. In conclusion, gold nanorods with controlled aspect ratios have been synthesized via a simple photochemical process. The amount of silver ions added to the system dictates the aspect ratio of the final ...
