Unraveling the role of superoxide radicals in CdS quantum dot instability
Photocorrosion hinders CdS development, this study shows that after 2 hours of irradiation in oxygen, H<sub>2</sub>O<sub>2</sub> yield of CdS reached 1.4 mmol g<sup>-1</sup>, while it was nearly undetectable under nitrogen. Capture experiments and electron paramagnetic resonance confirm that O<sub>2</sub> acts as an electron acceptor, forming radicals that oxidize and deactivate CdS.
