Influence of diffusion and deposition processes on the electrochemical formation of gold amalgam
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2019In this study, gold amalgam was prepared on a gold nanorods (Au Rs) modified ITO electrode through an electrochemical reduction of mercury ions (Hg2+), and the formation of amalgam was explored under steady and non-steady states. Under static system, Hg2+

Although the potential of gold amalgam as a nanoenzyme has been demonstrated, its practical utility has been limited by its low catalytic activity caused by the aggregation of Au nanoparticles (Au NPs). Thus, there is a need to further engineer Au NPs to
