We find that we made a mistake in the estimation of the H2 O2 concentration by the colorimetric method in our previous paper (J. Lin et al., Eur. Phys. J. D (2020) 74: 80) [1]. The H2 O2 concentration is estiamted by the colorimetric method based on the reaction of H2 O2 and Ti(SO4 )2 in strong acid (Ti4+ + H2 O2 + 2H2 O → H2 TiO4 + 4H+ ). The absorbance of the yellow-coloured H2 TiO4 at 410 nm is proportional to the reacted H2 O2 concentration [2–5], expressed as CH2 O2 = kI, (1) where k is the proportionality obtained by a calibration measurement, I is the absorbance at 410 nm of the H2 TiO4 formed by the reaction of H2 O2 and Ti(SO4 )2 . In Figure 4 of our paper (J. Lin et al., Eur. Phys. J. D (2020) 74: 80), we used a wrong k of 1.23, it should be 3.7. Therefore, the correct figure should be as Figure 1 here. Because the trends of the H2 O2 production change are our main concerns other than the absolute value in our paper, this corrigendum does not affect the validity
