Green Ammonia Generation with a Polypyridine Cobalt Complex and Visible Light.
Article in Journal of the American Chemical Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The use of a first-row transition metal complex and visible light was exploited to promote the photosynthesis of ammonia from nitrite ions. This is achieved in neutral aqueous solution by employing a cobalt polypyridine complex (CoL) within a light-driven catalytic scheme involving [Ru(bpy)3]2+ (where bpy = 2,2'-bipyridine) as the sensitizer and ascorbate as the electron donor. Under visible light irradiation, the resulting photosystem produces NH3 with a quantum yield up to 3% and a selectivity approaching 100%, achieving a maximum turnover number (TON) up to 2150. Transient absorption spectroscopy and density functional theory provided a robust mechanistic picture, showing that binding of the NO2- substrate occurs at the one-electron reduced metal complex, while also ascertaining the energetic feasibility of subsequent elementary reaction steps. All in all, this work uncovers the great potential of first-row transition metal polypyridine complexes toward the synthesis of chemicals of industrial relevance.
