A simple approach to the synthesis of hexagonal-shaped silver nanoplates

Abstract

This paper deals with the synthesis of hexagonal-shaped silver nanoplates with diameters ranging from 15 to 20nm along with a smooth nanobulk of 120nm. These nanoplates were prepared by a kinetically controlled solution growth method using mild reducing agent dextrose, polyvinylpyrrolidone (PVP M w 40k Da) as the capping agent and urea as a habit modifier and at a moderate temperature of 50 C. The crystal structure of the highly faceted particles consists mostly of (111) surfaces as revealed by both X-ray diffraction (XRD) studies and transmission electron microscopy (TEM). © 2011 G.
