(a) Cu L3-edge TFY spectra for ex situ and in situ electrodeposited Cu nanoparticles. (b) Cu L3,2-edge spectra acquired under in situ conditions. The black curve shows galvanostatic electrodeposition, while the red curve corresponds to the spectrum acquired during deposition followed by current interruption; the solid red line is recorded under applied current, and the red dashed segment (940–960 eV) indicates the intensity decrease after switching off the current, consistent with progressive Cu dissolution. (c) Potential evolution over 1000 s during in situ electrodeposition under a cathodic current density of −1.3 mA cm−2. Insert: image of the first 100 s.
