Abstract
Enhancing the dispersibility and recoverability of powdered catalysts is essential for developing efficient and cost-effective photocatalytic systems. Herein, β -FeOOH nanoparticles were in-situ deposited on commercially available filter paper (FP) to construct paper-based composite material ( β -FeOOH@FP). Results showed that the rod-like β -FeOOH nanoparticles were uniformly distributed in the FP matrix without destroying the crystalline structure of cellulose. The resulting β -FeOOH synthesized at 3 h presented the highest photoelectrochemical response and exhibited better suppression of electron–hole recombination, allowing more photogenerated electrons to participate in the reaction. The β -FeOOH@FP catalyst achieved a 94.1% photocatalytic degradation rate of tetracycline (TC) within 120 min compared to the pure β -FeOOH (42.2%) and FP (20.1%) under simulated visible light irradiation. Photocatalytic degradation kinetics also demonstrated that the rate constant of β -FeOOH@FP was 9.6 × 10 −3 min −1 , much higher than that of others. In addition, the resulting β -FeOOH@FP composite material exhibited excellent stability and reusability with a photocatalytic efficiency of over 90% after five cycles. These findings provide a simple and cost-effective strategy to improve the degradation performance of powdered semiconductor catalysts and pave a new way to develop cellulose-based nanocomposites with high photocatalytic efficiency.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
