Milling‐Induced Synthesis of BiOCl<sub>1‐<i>x</i></sub>Br<sub><i>x</i></sub> Solid Solution and Their Adsorptive and Photocatalytic Performance
Bibliographic record
Abstract
Abstract CH 3 COO (BiO) (denoted as Bi OA c) is one of the most easily obtained bismuth compounds and was for the first time proposed by our group as an effective UV light photocatalyst. Herein, Bi OC l 1‐ x B r x ( x refers to the feeding atomic ratio) were obtained using a facile solid state milling and subsequent water washing. More importantly, all of the as‐prepared Bi OC l 1‐ x B r x possessed better visible light photocatalytic activity to the corresponding ones obtained by previously reported solution route. Especially at an optimal x value of 0.5, the solid solution showed the highest photodegradation efficiency (~100%) for rhodamine B (RhB) with a concentration of 30 mg L −1 , whereas the degradation efficiency was only 63% over that obtained by solution route. Furthermore, the as‐prepared Bi OC l 0.5 Br 0.5 also exhibited excellent photodegradation activity for malachite green ( MG ). The superior photocatalytic performance of the as‐prepared Bi OC l 0.5 Br 0.5 could be attributed to its thinner sheetlike structures and highly exposed (001) facets, which enable effective separation of the photogenerated electrons and holes along the [001] direction. In addition, the as‐prepared Bi OC l 0.5 Br 0.5 revealed dramatic adsorption capacity for cationic dyes like MG , RhB and methylene violet ( MV ), as well as anion (Cr 2 O 7 ) 2− owing to electrostatic interaction between cationic dyes and negatively charged surface of Bi OC l 0.5 Br 0.5 , and positively charged surface in K 2 Cr 2 O 7 solution ( pH ≈ 3).

How this classification was reachedexpand
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.
