Abstract
Carbon dioxide (CO 2 ) capture is essential for mitigating climate change, but scaling existing technologies to address global CO 2 emissions will place significant demands on energy systems. To overcome this challenge, we present a photoelectrochemical flow system using anthraquinone-2,7-disulfonate (AQDS) as a sorbent, which is activated by sunlight to capture CO 2 under dark conditions and releases it upon reillumination. This system successfully cycled for 70 h, demonstrating both stability and efficiency. Inspired by solar rechargeable redox flow batteries, the system expands on current solar-driven CO 2 capture technologies by enabling CO 2 release via photodesorption at 0 V vs OCV. While the system is still in its early stages, it presents a promising addition to the range of photo- and electrically driven CO 2 capture methods, with potential for future advancements toward more effective and scalable CO 2 capture solutions.

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
