“…Taking into account their corresponding stripping peaks, A2 and A3, and based upon a three-electron process for the reduction of Sb, the coverage for peak C1(C2) is calculated as 0.78 monolayer (ML). This result is similar to that obtained in our previous study on CoSb 3 [23]. The second reductive peak (C3) should correspond to both HER and bulk deposition of Sb.…”

International audienceThe present paper is a detailed study on the deposition of Sb2Se3 thin films by electrochemical atomic layer epitaxy (EC-ALE). The related electrochemical aspects have been deeply investigated by means of cyclic voltammetry, anodic potentiodynamic scanning, and coulometry. The UPD layer of Se was obtained by first depositing both UPD Se and a small amount of bulk Se and then stripping the redundant bulk Se in blank solutions. A "two times rinsing" method was developed to avoid the formation of red Se during the rinsing process. The deposition parameters were determined for the first three EC-ALE cycles, and from these values, a nanofilm containing Sb and Se atoms has been obtained. By scanning electron microscopy and coulometry, it was shown that the deposit is compact and it has a stoichiometry very close to that of Sb2Se3. The Raman spectral analyses show that the deposit is made of Sb2Se3 nanoclusters

“…All electrochemical experiments are performed with the EC-ALE equipment developed by us and depicted in our previous work [23]. The electrochemical flow cell is close to those described by the Stickney [24][25][26] and Zhu-Yang [27] working groups.…”

“…The first cathodic peak, C 1 , can be associated with underpotential deposition, UPD, [26,27] of tin on gold surface [28], similar to that already described for cobalt and antimony on gold [29] or silver and copper on gold [14]. The driving force for UPD is the formation of a compound that is energetically favoured relative to the bulk elements.…”

“…Therefore, upd of a metal monolayer onto polycrystalline or single-crystal substrates of a foreign metal has been studied intensively. These investigations included various substrates such as Au, Pt, Ag, Cu, Rh, Ru, Pd, and many deposited ions like Ag + [13,14], Cu 2+ [15][16][17][18][19][20][21][22][23][24], Cd 2+ [25], Pb 2+ [26][27][28][29][30], Tl + [31][32][33][34], Cd 2+ [35,36], Hg 2+ [37], Sn 2+ [38,39], Bi 3+ [30,[40][41][42][43][44][45], Ge 4+ [46][47][48], Sb 2+ [49][50][51], and Ni 2+ [52]. The charge corresponding to the upd permits researchers to estimate the amount of deposited metal.…”

Probing the Surface of Noble Metals Electrochemically by Underpotential Deposition of Transition Metals

The advances in material science have led to the development of novel and various materials as nanoparticles or thin films. Underpotential deposition (upd) of transition metals appears to be a very sensitive method for probing the surfaces of noble metals, which is a parameter that has an important effect on the activity in heterogeneous catalysis. Underpotential deposition as a surface characterization tool permits researchers to precisely determine the crystallographic orientations of nanoparticles or the real surface area of various surfaces. Among all the work dealing with upd, this review focuses specifically on the main upd systems used to probe surfaces of noble metals in electrocatalysis, from poly‒ and single-crystalline surfaces to nanoparticles. Cuupd is reported as a tool to determine the active surface area of gold‒ and platinum‒based bimetallic electrode materials. Pbupd is the most used system to assess the crystallographic orientations on nanoparticles’ surface. In the case of platinum, Bi and Ge adsorptions are singled out for probing (1 1 1) and (1 0 0) facets, respectively.
