Abstract

Gold nanostructures such as nanoparticles, nanowires, or nanotubes are highly preferred structures in electrochemical studies and can be produced by electrodeposition. This study points out that the shapes and electrochemical behaviour of electrodeposited gold nanostructures can be varied by adjusting multi-walled carbon nanotube (MWCNT) ratio in electrodeposition solution. For that, gold nanofilms on the glassy carbon electrode surface were formed from HAuCl₄ solution in the presence and absence of MWCNT. In this study, the gold concentration was fixed at 0.4 ppm (10.0 mM) and only MWCNT concentration was varied. The prepared electrode surfaces were characterized and compared with each other from the point of view of electrochemical, microscopic, and spectroscopic properties. Ultimately, it was shown that each prepared electrode had different properties.

通过电沉积合成树突状金纳米结构的最新方法

摘要

金纳米结构，例如纳米颗粒，纳米线或纳米管，在电化学研究中是高度优选的结构，可以通过电沉积制备。这项研究指出，可以通过调节电沉积溶液中的多壁碳纳米管（MWCNT）比例来改变电沉积金纳米结构的形状和电化学行为。为此，由HAuCl ₄形成了玻碳电极表面的金纳米膜。在存在和不存在MWCNT的情况下的溶液。在这项研究中，金的浓度固定为0.4 ppm（10.0 mM），只有MWCNT浓度发生变化。从电化学，微观和光谱性质的观点，对所制备的电极表面进行表征并相互比较。最终，表明每个制备的电极具有不同的性质。
