The aim of this work was to carry out the process of photoelectrochemical production of hydrogen while examining the properties of the SnS2 electrode with the addition of various hole scavengers. Different concentrations of 5-aminosalicylic acid and ascorbic acid were used in 0.1 M NaCl solution as the basic electrolyte. Measurements were performed using the following methods: linear polarization, cyclic voltammetry, electrochemical impedance spectroscopy and chronoamperometry for unilluminated and illuminated electrodes. Measurements were performed through three cycles. Given that the SnS2 electrode absorbs in the visible part of the spectrum, an LED lamp was used as a light source. As an additional characterization of the sacrificial agents, measurements were carried out to investigate the antioxidant properties against the O2-‧ radical. The results obtained by the linear polarization method indicate the photoactivity of the material due to the appearance of photocurrents for the illuminated electrodes. Also, using the method of linear polarization and chronoamperometry, it was shown that the highest amount of current is obtained in the first measurement, while in other measurements we have lower amounts of current due to photocorrosion of the active material. In comparing the currents for pure 5-ASK and the combination of 5-ASK and AA, it can be concluded that their combination results in higher amounts of current. This research result is important because combinations of sacrificial agents often appear in nature, so it was important to examine their interaction. Impedance measurements show that the impedance is lower for the illuminated electrodes, i.e. the charge transfer resistance is lower than for the non-illuminated electrodes, which confirms the good photoactivity of the electrode. The antioxidant properties were tested using the method of cyclic voltammetry, which indicates that increasing the concentration of 5-ASK in the solution of 5-ASK and AA will contribute to a better quenching of the superoxide radical.
