Exploration of Ag decoration and Bi doping on the photocatalytic activity α‐Fe<sub>2</sub>O<sub>3</sub> under simulated solar light irradiation
Bibliographic record
Abstract
Abstract In the present investigation, silver decorated and bismuth doped α‐Fe2O3 (Ag/Bi‐Fe2O3) was successfully synthesized using the co‐precipitation method. The size, shape, surface area, and magnetic properties were characterized by XRD, FE‐SEM, EDX, BET, VSM, and UV‐Vis‐DRS techniques. The synthesized nanoparticles were used as a photocatalyst for the degradation of rose bengal (RB) dye under simulated solar light irradiation. Ag/Bi‐Fe2O3 showed the better photocatalytic activity of 97.11 % within 135 min when compared to Bi‐Fe2O3 and Ag‐Fe2O3. The superior photo‐catalytic activity of Ag/Bi‐Fe2O3 was mainly ascribed to visible light absorption and the suppression of photo‐generated electron‐hole recombination. Ag/Bi‐Fe2O3 was found to be a stable photocatalyst during recycling experiments. Besides, the magnetic property of Ag/Bi‐Fe2O3 makes it an ideal candidate for separation and recovery during recycling.

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.
