Abstract

fetched live from OpenAlex

Zinc phthalocyanine (ZnPc)/ZnO and zinc tetrasulfonated phthalocyanine (ZnTSPc)/ZnO were synthesized by an in situ process. The products were characterized by XRD, UV-Vis, FTIR, and Fluorescence spectroscopy techniques. The results show that ZnPc, ZnTSPc are synthesized on the surface of ZnO particles during the in-situ process. The changes of fluorescence intensity and lifetime indicate that there is no electron transfer between ZnPc and ZnO, while the electrons of the excited state of ZnTSPc are easily injected into the ZnO conduction band by means of sulfonated group (-SO3-Zn), and the rapid electron transfer rate of ket between ZnTSPc and ZnO is equal to 6.1×107 s-1 in 1.0mol% (ZnTSPc∶ZnO in mol) ZnTSPc/ZnO. Compared with pure ZnO, ZnPc/ZnO shows high photocatalytic activity for the photocatalytic decolorization of RhB under visible-light irradiation by transferring energy from ZnPc to oxygen molecule and forming 1O2, while ZnTSPc/ZnO reveals higher photocatalytic activity due to 1O2 formed by means of transferring energy from ZnTSPc to oxygen molecule and O2-formed by transferring electron from ZnTSPc to ZnO.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
