Gold nanoparticles can be synthesized at room temperature using HAuBr4, achieving size control from 5-30 nm.
The synthesis process differs between HAuCl4 and HAuBr4, with the latter producing larger nanoparticles and varying shapes.
HAuBr4 proves to be effective as a catalyst, particularly in water treatment applications like reducing 4-nitrophenol.
This research clarifies the advantages and disadvantages of using HAuCl4 versus HAuBr4 in the synthesis of gold nanoparticles.
