Abstract

Atomic force microscopy (AFM) has been applied to investigate in situ the Hg/Au amalgam process by depositing the excess Hg atoms on an Au electrode surface in an acidic solution, which has led to form an Au/Hg alloy layer. We found that the formation of alloy layer proceeded through an island-growth mechanism and the growth of these islands is always fed by dissolution of nearby gold clusters. Based on AFM observations, a simple model of the Hg/Au amalgam process is proposed.

Real-time composition and deposition depth profile of metal alloys using electrochemical surface plasmon resonance

The background experiment in the electrolyte solution without Hg2+ (dot line) showed a small SPR dip shift (∼0.1°), which could be due to the charge of the double layer [10,11]. As previous works have reported, the Hg atoms could diffuse into the bulk Au to form the Hg–Au alloy once the coverage of the Hg exceeds one monolayer [12]. To observe the alloying process, the electrodeposition of Hg onto the Au film was performed at a constant potential of 0.1 V using the FI-EC-SPR method.
Electrodeposition is one of the most conventional techniques for fabricating alloyed nanofilms. However, given the lack of in situ and real-time techniques in determining the composition and deposition depth of the alloyed nanofilms, effective optimization of alloying effects is difficult, which limits the application of electrodeposition. In the current study, electrochemical (EC) surface plasmon resonance (SPR) was equipped with home-compiled calculation software to achieve the real-time composition and deposition depth profile of the surface-alloyed nanofilms. The results obtained from the Hg–Au alloy proved that EC-SPR is capable of presenting a real-time profile of the alloying process. The in situ and real-time determination will facilitate the effective fabrication of well-controlled alloyed nanofilms and improve the application of the EC method.
In situ scanning tunneling microscopy of electrodeposition of mercury on a well-ordered Ir(1 1 1) electrode
2003, Journal of Electroanalytical Chemistry
Electrodeposition of Hg at a well-ordered Ir(1 1 1) electrode has been examined by linear sweep voltammetry (LSV) and in situ scanning tunneling microscopy (STM) in aqueous 0.1 M HClO₄ containing dilute Hg(ClO₄)₂. The results of LSV revealed multiple peaks, presumably due to underpotential deposition and diffusion-limited bulk deposition. In situ STM unveiled the details of bulk Hg deposition at bare and iodine-modified Ir(1 1 1). The compositions of the Ir(1 1 1) surface could dominate the morphology of the Hg film. An iodine adlayer rendered layer-by-layer deposition of Hg till the sixth layer when 3D island growth prevailed. High-quality STM atomic resolution identified a well-ordered iodine overlayer residing on top of the Hg film, strongly suggesting that the Hg film was crystalline. At a bare Ir(1 1 1), Hg deposition was also layer-by-layer but only to a thickness of three layers. Without the iodine adlayer, the Hg film was, however, seriously pitted and it was not possible to achieve atomic resolution.
Surface mediated Ag-Hg alloy formation under ambient and vacuum conditions - AFM and XRD investigations
2002, Applied Surface Science
Thin Ag films deposited under UHV conditions on a glass support were exposed to Hg vapor at 298 K under two different conditions: vacuum, and ambient atmosphere. The influence of the amalgamation process on film topography was studied by the atomic force microscopy (AFM) method, while the composition of the amalgams was determined by means of X-ray diffraction (XRD). The obtained results indicated the different mechanism of Ag₂Hg₃ alloy formation depending on whether the amalgam is formed in a vacuum or under ambient atmosphere. This is discussed as a consequence of the influence of oxygen and different kinetics of the amalgamation process performed under both conditions. Heating of amalgam leads to gradual reconstruction of the alloy (370 K) and finally its decomposition (500 K), leaving strongly modified, discontinuous silver film. The ultimate nanostructure of the film depends on the transport mechanism of the silver nanounits during the amalgamation process. Therefore, Ag–Hg alloy formation and decomposition seems to be a practical and promising method for the preparation of discontinuous thin silver films of significant thickness and mesoscopic structure.
Atomic force microscopy of Au/Hg alloy formation on thin Au films
1997, Applied Surface Science
Atomic force microscopy was applied to the study of thin Au films deposited under ultra-high vacuum conditions on a glass support maintained at 78 K. A variety of thin gold film structures were thus determined and characterized ranging from (i) nanometric isolated gold islands, (ii) nanometric gold structures, to (iii) continuous gold films, all depending on the amount of Au deposited. The influence of the amalgamation process on the thin Au films topography was studied. The fundamental importance of surface defects on the rate of amalgamation was clearly seen. The movement of small Au islands on glass obtained as the result of thermal decomposition of $Au Hg$ alloys was observed.
In-situ atomic force microscope observation of stripping of mercury from Hg Au alloy films in acidic media
1995, Surface Science
We report the first in-situ atomic force microscope (AFM) observation of the stripping process of mercury occurring in $Hg Au$ alloy films. AFM images revealed that stripping preferentially occurred at the edges of defect sites during the initial stages and this process directly led the electrode surface to roughen with a multiple pit-like structure on nanometer scale. The formation mechanism of such structure is also discussed.
