Stabilization of triangular and heart-shaped plane silver nanoparticles using 2-thiobarbituric acid
Source abstract
Abstract
The synthesis of silver non-spherical structures like nanotriangles, nanohexagons, and nanodisks, etc., follows a kinetic control that strongly depends on the nature and concentration of the reagents. By using sodium borohydride in a low molar ratio respect to the Ag+ source for working under kinetic control, it was possible to obtain different plane nanostructures which in turn could be stabilized by the use of the substituted mercaptopyrimidine 2-thiobarbituric acid. In addition, the use of this thiol allowed the stabilization of an unreported shape that could be an intermediate structure in the shape evolution of nanotriangles through nanodisks. This new particle, with 200–300 nm length and 6 nm height, is named “nanoheart” due to its heart-shaped resemblance.
