Factors Affecting the Performance and Applicability of SrTiO<sub>3</sub>Photoelectrodes for Photoinduced Cathodic Protection
Bibliographic record
Abstract
In this work, various factors affecting the applicability and performance of prepared SrTiO3 photoelectrodes for photoinduced cathodic protection (CP) were investigated. The capability of the photoelectrode for photoinduced CP depends on the type of steels to be protected. A higher photo current density is required to cathodically protect X52 carbon steel than 304 stainless steel. Threshold areas of the photoelectrode relative to that of the cathode exist for both steels to enable photoinduced CP. The threshold area ratio of the SrTiO3 photoelectrode to X52 carbon steel is 8: 1 in 3.5 wt% NaCl solution, while, for 304 stainless steel, the area ratio of 1: 1 is sufficient for photoinduced CP. The photoinduced CP performance depends on the hole scavenger used in the photoelectrode cell. Na2S is an effective hole scavenger, and both X52 carbon and 304 stainless steels are cathodically polarized by photoelectrons to sufficiently negative values for a full CP. Moreover, the SrTiO3 photoelectrode can fully protect X52 steel only when the light intensity is up to 125 mW/cm2, while a light intensity of 50 mW/cm2 enables a full CP on 304 stainless steel. The photoinduced CP performance is also subject to the corrosivity of the solutions.

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.
