Abstract

fetched live from OpenAlex

This study presents the synthesis of black anatase in air and its use for the fabrication of a reusable electrode for the photocatalytic degradation of Rhodamine B (RhB) under visible-light. Characterization techniques such as X-ray diffraction, Raman spectroscopy, and Transmission Electron Microscopy (TEM) were used to analyze the properties of black anatase. The immobilization of black TiO 2 on a glass substrate eliminates the need for post-treatment recovery of the photocatalyst. Enhancement of photocatalytic activity was achieved by depositing a 4 nm platinum layer on the black anatase TiO 2 electrode. Activation of the photocatalytic process (λ ≥ 400 nm) was conducted with a solar simulator, and the degradation of RhB was monitored through visible absorption and time-resolved fluorescence spectroscopy, revealing degradation efficiencies of 94 % and 89 % after 40 and 60 min, respectively. These results are attributed to the elevated levels of oxygen vacancies and the Schottky barrier formed between the platinum layer and black anatase. The methodology's simplicity and the significant photocatalytic efficiency suggest potential for widespread application in solar-driven photocatalytic degradation.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
