Abstract
Abstract The conversion of CO 2 into CO, CH 4 and other hydrocarbons through solar energy can alleviate the energy shortage problem. We design a novel photocatalyst with S defects CuIn 5 S 8 @MoSe 2 hollow structure. The interlayer‐expanded MoSe 2 can increase the adsorption of intermediates. The unique hollow structure can improve the light utilization efficiency and the electron–holes separation. CuIn 5 S 8 with S vacancies in bimetallic sites has high selectivity and photocatalytic reduction of CO 2 activity. Therefore, S vacant CuIn 5 S 8 confined in a few‐layers MoSe 2 with interlayer‐expanded hollow heterostructures exhibit super performance for photocatalytic CO 2 reduction. After 8‐h light reaction, the outputs of CO and CH 4 for the 15.3 wt% CuIn 5 S 8 @MoSe 2 sample containing S vacancies (V s ) are 30.4 and 14.7 µmol·g −1 , respectively. The mechanism is also investigated in detail through in situ Fourier transform infrared spectroscopy technology.

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 it
