Abstract
Abstract In this paper, a plasmonic photo‐assisted electrochemical sensor, Au anchored on two‐dimensional (2D) graphitic carbon nitride (g‐C 3 N 4 )/reduced graphene oxide (rGO) nanosheets (Au/g‐C 3 N 4 /rGO), was facile fabricated. The morphology and structure of the composite are characterized by transmission electron microscope, X‐ray photoelectron spectroscopy, X‐ray diffraction and ultraviolet–visible spectrophotometer (UV–Vis). Based on the semiconductor of g‐C 3 N 4 and optical properties of surface plasmon resonance for Au, the as‐prepared Au/g‐C 3 N 4 /rGO showed high sensitivity for the detection of trace lead ion [Pb(II)] by differential pulse anodic stripping voltammetry in the presence of visible light illumination. Under optimized conditions, the limit of detection (signal‐to‐noise ratio ( S / N ) = 3) Pb(II) detection can be low to 0.1 nmol·L −1 . In addition, the interference research and real soil sample detection were measured to confirm the possibility of practical applications.

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
