Capping agent promoted oxidation of gold nanoparticles: cetyl trimethylammonium bromide.
Capping agents, key for nanoparticle stability, may hugely influence chemical behaviour. We show that differently capped gold nanoparticles, with either citrate or cetyl trimethylammonium bromide (CTAB) capping agents, show qualitatively different electron transfer properties. Specifically through cyclic voltammetry and nanoimpact studies the CTAB promoted dissolution of gold nanoparticles is s...
متن کاملAnalysis of the Evolution of Tannic Acid Stabilized Gold Nanoparticles Using Mie Theory
Spherical gold nanoparticles (GNPs) have been synthesized in aqueous solutions using sodium citrate (SC) and tannic acid (TA) as reducing and stabilizing agents. Upon addition of TA and compared to the GNP TA-free aqueous solutions, a reduction of the GNPs size and consequently a dramatic change of their optical properties have been observed and quantitatively analyzed using Mie theory. An incr...
متن کاملThe Coordination Chemistry at Gold Nanoparticles
Nas nanopartículas de ouro, as propriedades químicas e físicas são ditadas principalmente pelos átomos da superfície, os quais podem interagir com espécies doadoras-aceitadoras, ou ligantes, da mesma forma que os complexos metálicos correspondentes. Além disso, os elétrons podem entrar em ressonância com a luz incidente dando origem aos plasmons de superfície, que levam à intensificação do camp...
متن کاملCapping-agent-free synthesis of substrate-supported porous icosahedral gold nanoparticles.
We report a new capping-agent-free strategy for the synthesis of substrate-supported porous icosahedral Au nanoparticles (NPs) with rough naked surfaces, based on the crystallization from substrate-supported thin solution layers followed by solid-phase thermolysis. The plasmonic properties of icosahedral Au NPs have been studied using single particle dark-field scattering microscopy and spectro...
متن کاملThe Stage Dependent Effect of Capping Agent Introduction in the Synthesis of Magnetite Nanoparticles
In this paper, three techniques to obtain capped magnetite nanoparticles were compared. In the formation of magnetite nanoparticles via the co-precipitation route, capping agents were introduced pre-, simultaneously with, or post-addition of the precipitating agent, ammonia. The amino acids L-glutamine and L-glutamic acid were used as the capping agents. Characterization via TEM, pXRD, EDX, and...
