Abstract

fetched live from OpenAlex

Abstract Photo(electro)catalytic nitrogen fixation is considered as a competing alternative for the Haber–Bosch (HB) process due to the direct production of ammonia (NH 3 ) from nitrogen and water with zero carbon dioxide emission, which has made it a very hot research topic in recent years. Particularly, photo‐driven nitrogen reduction has been attracted to a specific focus in the scientific community since it can be powered by limitless solar energy at ambient conditions. However, unsolved challenges have remained to date such as, electron–hole separation, low quantum efficiency, weak visible light harvesting, catalytic selectivity, N 2 adsorption, and activation. In this Review, the recent achievements and related approaches toward nitrogen fixation are presented. In addition, the discussions on mechanistic photofixation of nitrogen, catalytic engineering design, and the outlook for enhancing the photocatalytic performance of ammonia photosynthesis are also devoted. Finally, the emerging trend of advanced photo(electro)catalysts for nitrogen fixation is proposed.

Full frame distilled prediction

Teacher imitation

Not 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.
