Interfacial solvation pre-organizes the transition state of the oxygen evolution reaction.
Article in Nature chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 8 papers.
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 sluggish kinetics of the oxygen evolution reaction are an energetic bottleneck for green hydrogen production via water electrolysis. The reaction proceeds over a surface that undergoes (frustrated) phase transitions to accommodate bias-dependent excess charge. Here we perform Arrhenius analysis of common catalysts and correlate the activation energy and pre-exponential factor with the oxide's structural adaptation via operando X-ray absorption spectroscopy and high-energy X-ray diffraction. We observe that the kinetics switch from a regime that is probably dominated by interfacial solvation to one where the surface energetics take over. This happens right at a transition potential between the α or β phases into the γ-crystal structure of Ni (oxy)hydroxides and when spectroscopic fingerprints of key intermediates emerge. Importantly, this turning potential is independent of the loading or the surface area and informs on the intrinsic catalyst activity. These results suggest that the catalyst activity is intrinsically linked to the initial interfacial solvation (pre-)step.
