the reduced ag clusters and the longer the reacting time the bigger the reduced ag clusters in this preferred embodiment all the steps are identical to those of the preferred embodiment 17 except the pdcl 2 is replaced by haucl 4 for the au metallic ion the higher the temperature the bigger the reduced au atoms and the longer the reacting time the bigger the reduced au atoms fig2 is the x ray diffractometer testing result of au nanoparticles deposited from polystyrene particles the figure shows demonstrates that the surface of the polystyrene particles of the present invention indeed deposits gold nanoparticles so fig2 shows gold comprising different crystallines in this preferred embodiment all the steps are the identical to the preferred embodiment 17 except the pdcl 2 being replaced by h 2 ptcl 6 for the pt metallic ion the higher the temperature the bigger the reduced pt atoms and the longer the reacting time the bigger the reduced pt atoms in this preferred embodiment all the steps are the identical to the preferred embodiment 17 except the pdcl 2 being replaced by rucl 3 for the ru metallic ion the higher the temperature the bigger the reduced ru atoms and the longer the reacting time the bigger the reduced ru atoms the polymerization of the present invention not only can control the diameter size.
