Preparation and Sunlight Photocatalytic Properties of TiO_2-CoFe_2O_4 Magnetic Composite Materials
Bibliographic record
Abstract
A TiO2-CoFe2O4 composite photocatalyst was prepared by one-step method with ultrasound technique using TiCl4、trivalent iron salt and divalent cobalt salts as precursors.The properties of the sample were characterized by VSM、XRD、TEM and UV-Vis techniques.The photocatalyst activity was evaluated by using methyl orange aqueous solution as the model contaminant in the sunlight.The results indicated that the TiO2-CoFe2O4 composite photocatalyst showed good magnetic properties and the saturation magnetization was 212 Gs.The TiO2 and CoFe2O4 of the samples existed as anatase phase and spinel structure,respectively.The diameter of the TiO2-CoFe2O4 particles was in the range of 40～50 nm.The spectrum response was from UV to visible region and the absorbance intensity remarkably increased.The photocatalyst showed highly photocatalytic activity in the sunlight and the activity was still good enough after 3 cycles.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
