Turning weak into strong:on the CTAB-induced active surface growth
文献摘要：
Discovering new methods and principles in the inequivalent growth of equivalent facets is of great significance for going beyond symmetrical nanocrystals and for out-of-box exploration.In this work,we demonstrate that a middle ground exists between the traditional weak ligands and the strong ligands with unusual growth modes.By modifying the seed concentration during the growth of pentagonal Au nanorods,the typical weak ligand cetyltrimethylammonium bromide(CTAB)is made strong,leading to notches of restricted growth and even the active surface growth mode.In-depth investigation in the link between growth kinetics and ligand packing reveals the principle of their interplay that the on-off dynamics of the ligands only allows for a certain limit of materials deposition rate.Beyond this limit,the growth materials build up and are then diverted elsewhere,leading to inequivalent growth.The fact that a freshly grown surface has few ligands promotes the active surface growth,focusing the growth materials onto a few sites.We believe that the knowhow of interfering ligand packing via growth kinetics would offer a powerful tool of synthetic control,where the facet-and curvature-dependent ligand packing is expected to be useful synthetic handles.
