Over-oxidation

WebMar 27, 2024 · Here, ZnIn2S4 nanosheets with dual vacancies (DZIS) were synthesized using a facile hydrothermal and alkali-etching strategy. In the absence of cocatalysts, an outstanding photocatalytic hydrogen evolution rate (4650.1 µmol h−1) coupled with a selective benzylamine oxidation rate (7386.7 µmol h−1) was obtained over DZIS. WebAdding secondary anti-oxidants to the polymer may help to minimize this over-oxidation. Pinking can also be caused by interactions with pigments. The presence of titanium +4 in titanium dioxide based white masterbatch colorants can trigger over-oxidation of the hindered phenol anti-oxidant.
