一種 CTAB the see d solution was made by i njecting a f reshly prepared, i ce-cold aqueous NaBH 4 sol ution (0.01 M, 0.6 mL) into an aqueous mixture compos ed of H AuCl4 (0 .01 M, 0.25 mL) and CT AB (0.1 M, 9.75 mL), fo llowed by rapid inversion mixing for 2 min. This see d solution was kept at room tempe rature for more than 2 h before use. The g rowth solu tion was made by the sequential add ition of aqu eous H AuCl4 (0.01 M, 2 mL ), AgNO 3 (0.01 M, 0.6 mL ), HCl (1 .0 M, 0.8 mL), and ascorbic acid (0.1 M, 0.32 mL) solu tions into an aqu eous CTAB (0.1 M, 40 mL ) solution. The resul tant solution was mix ed by swirli ng for 30 s, followe d by the addition of 0.3 mL of the see d solution. The resultant reaction solu tion was gently m ixed by inversion for 2 min and then left undis turbed overni ght |
