Formation of one-dimensional crooked gold nanocrystals by electrochemical technique with surfactant solution

This study demonstrates the synthesis of one-dimensional (1D) crooked gold (Au) nanocrystals by an electrochemical method with surfactant. For example, the primary surfactant may be cetyltrimethylammonium bromide (CTAB), and the auxiliary surfactant may be tetradodecylammonium bromide (TTAB) with isopropanol (IPA) solvent. The formation of crooked Au nanocrystals was induced by aggregation of many small Au nuclei between the several large Au nanoparticles during growth, causing the small Au nuclei to link to the large Au nanoparticles forming crooked Au nanocrystals.
