Sažetak
In-situ Electrochemical Scanning Tunnelling Microscopy (EC-STM) has been used for characterization and determination of FeS nanoparticles (NPs) at an Au(111) electrode in NaCl solutions oversaturated with FeS. In parallel, voltammetric measurements in different electrode systems (Hg and Au) were conducted. Particle deposition was studied in relation to variations in applied and scanning electrode potentials over a range from 0.1 to -1.5 V vs. Ag/AgCl. EC-STM images obtained on the Au(111) electrode revealed the presence of FeS NPs, accompanied by a drastic transformation in the electrode’s surface topography during scanning from 0.1 V to -1.2 V. A majority of FeS NPs (diameter 2–5 nm) were detected in the potential range from -0.15 to -0.25 V vs. Ag/AgCl. The EC- STM results are in very good agreement with previous voltammetric measurements at Hg and Au electrodes. The combination of in-situ EC-STM and cyclic voltammetry complementary techniques appears to be a powerful tool for the characterization of complex electrochemical systems such as chalcogenide NPs in aqueous solutions.
