One pot, facile synthesis of hierarchical silver nanostrip assembling architecture

Here we present a simple wet-chemical approach to synthesize flower-like silver nanostrip assembling architecture at room temperature. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) images indicate that these microstructures with the diameter of ∼500 nm exhibit hierarchical characteristic. X-ray diffraction (XRD), energy-dispersed X-ray spectroscopy (EDX) and Raman spectroscopy indicate that poly (o-diaminobenzene) (PDB) also exists in the silver hierarchical microstructure. The roles of the poly(N-vinyl-2-pyrrolidone) (PVP) concentration on the hierarchical microstructure synthesis have been systematically investigated. Due to their hierarchical characteristic and high surface-to-volume ratios, these microstructures are expected to find potential applications in bioelectrochemistry.
