One-step synthesis of silver nanoplates with high aspect ratios: using coordination of silver ions to enhance lateral growth

Abstract

A coordination-based strategy was employed to produce Ag nanoplates with high aspect ratios. Ag nanoplates were synthesized in the presence of acetonitrile, which served both as the co-solvent and as the ligand to form complexes with the Ag+ ions.

One-step green synthesis of 2D Ag-dendrite-embedded biopolymer hydrogel beads as a catalytic reactor

“… 51 Therefore, the formation of nanoplates is not thermodynamically favored, and nanoplate structures can only be obtained by inducing reactions under kinetically controlled conditions. 52 Specifically, when the reduction rate of Ag + ions is low, the formation of nanocrystals is governed by reaction kinetics, not thermodynamics; thus, anisotropic nanostructures such as nanoplates can be formed. 53 Because the reducing power of alginate (the reductant in the present study) at room temperature is low, Ag nanoplates were formed at the beginning of the reaction.…”

Completely green synthesis of rose-shaped Au nanostructures and their catalytic applications

“…Under kinetically controlled reaction conditions based on a single-step synthesis method, the lateral growth of nanoplates tends to stop when the nanoplates reach a certain size. 64 As far as we know, nanoplates synthesized by conventional single-step solution-phase synthesis pathways have rarely grown to more than 500 nm in lateral size. 65 In addition, the amount of PVP is not sufficient to effectively cap the top and bottom {111} surfaces of the nanoplates in the LLP reaction region; consequently, the newly generated Au nanoplates stack on the surface of the existing large nanoparticles, forming layered structures.…”
