Abstract

In competition-based experiments, 1,4-benzoquinone (BQ) has been a frequently applied compound for determination of the role of O2− radicals. In those studies, only the influence of BQ (as a competitive O2− scavenger) on the degradation of a model compound (substrate) was investigated. Our goal was to develop a new, simple method monitoring a characteristic product of the reaction between the superoxide radical ion and BQ during heterogeneous photocatalysis. Interestingly, based on our results, if the concentration of BQ exceeds that of dissolved oxygen, it reacts with photogenerated electrons rather than with O2− radicals. During this process, it is quantitatively reduced to 1,4-hydroquinone (H2Q), the degradation of which was found to be dependent of the presence of O2− radicals. The photocatalytic transformation of both compounds (BQ, H2Q) was systematically investigated in anoxic and oxic atmosphere. Two new methods requiring only fluorescence measurements have been suggested: one for the determination of electrons with BQ (under anaerobic conditions) and another for the measurement of O2− radicals with H2Q.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
