Spectroelectrochemistry in the presence of Ni phet (a), Ni Sch (b), Co Sch (c) and Mn phet (d). For the conditions see: Table S3 and Fig. S2. SEM images of FTO after the amperometry in the presence of Ni phet (e), Ni Sch (f), Co Sch (g) and Mn phet (h). For the conditions see Table S6. UV-vis spectra for Ni phet under potential. The conditions: in the phosphate buffer (20.0 mL; 0.25 M) at pH = 11.0 during 28 hours. The scale bars for SEM images are 200 nm. Arrows show an increase for UV-vis absorbance spectra.
