摘要	A great deal of progress has been made with regard to the morphology and growth mechanism of metal nanostructures, here we report a novel method to control the morphology of silver nanostructures by galvanic replacement reaction with the assistance of boric acid. Silver nanotubes and nanocombs were obtained by varying the concentration and pH value of boric acid. The growth status of silver nanostructure were captured during the process, meanwhile, a novel growth mechanism of silver nanocombs and nanoflowers was proposed. We hypothesized that the boric acid acts as a modified electrode and template molecule in the system. The possible molecular configuration of boric acid, the modification and adsorption of boric acid on the electrode during the galvanic replacement were also investigated. Finally, this paper has demonstrated the versatility of a simple, green and conceptually novel naturally occurring template approach for the controllable synthesis of metal nanostructures.
