Electrocatalysts for ammonia production and nitrogen cycle management in Zinc-NOx batteries: Progress, challenges, and future perspectives
Bibliographic record
Abstract
This review provides a comprehensive overview of the recent progress in zinc-NO x (Zn-NO x ) chemistries , focusing on their basic reactions, detection methods for various products, and the development of high-performance electrocatalysts . The electrocatalysts for NO x reduction in Zn-NO x batteries are systematically discussed, highlighting their synthesis strategies, structure-activity relationships, and catalytic mechanisms. Key performance metrics, such as ammonia yield, Faradaic efficiency, and power density, are also compared for the most promising electrocatalysts in each category. As such, Zn-NO x chemistries, where NO x represents nitrate (NO 3 − ), nitrite (NO 2 − ), or nitric oxide (NO), have emerged as promising systems for electrochemical ammonia production, nitrogen cycle management, and energy storage. Converting NO x waste into valuable ammonia is crucial for reducing environmental pollution and generating a useful product. Additionally, energy storage is essential for integrating renewable energy sources into the power grid, and Zn-NO x batteries offer a unique solution to this challenge, paving the way for the practical implementation of Zn-NO x batteries in sustainable ammonia production and energy storage. The novelty and significance of Zn-NO x batteries lie in their ability to simultaneously address environmental concerns and energy storage needs, setting them apart from other existing technologies. With continued research efforts and innovations in electrocatalyst design and battery engineering, Zn-NO x batteries hold great promise for contributing to a more sustainable and energy-efficient future.

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.
