Facile fabrication of H<sub>2</sub>BDC‐NH<sub>2</sub> modified anatase TiO<sub>2</sub> for effective photocatalytic degradation of azo dyes
Bibliographic record
Abstract
abstract The 2‐amino benzene dicarboxylic acid (H2BDC‐NH2) modified TiO2 was prepared via hydrothermal method. The surface areas of unmodified and modified TiO2 were 23.206 and 231.908 m2/g, and the according light absorption range changed from 400 nm to 540 nm. The modified TiO2 exhibited 3 times higher visible‐light photocatalytic degradation efficiency for four types of azo dyes than unmodified TiO2 and commercial P25. The ligand H2BDC of modified TiO2 generated photoelectrons and holes under visible light irradiation, producing and active sites for the dye degradation. Moreover, the modified TiO2 showed excellent stability, which suggests the as‐prepared composite to be a promising photocatalyst.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
