An Experimental Benchmark for the Barrier Height of an On-Surface Reaction: Hydrogen Oxidation on Pt(332).

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
Developing predictive theories for the rates of reactions between surface-bound molecules is a central challenge to understanding many important phenomena including: heterogeneous catalysis, electrocatalysis, nanofabrication, and corrosion. To meet this challenge, chemically accurate benchmarks to test theoretically derived reaction rates and barrier heights are essential, but few exist. Here, we determine from experiment an accurate zero-point-energy corrected barrier height, 0.76 ± 0.03, for the reaction O* + H* → OH* occurring at atomic Pt B-type step sites, the rate limiting step of hydrogen oxidation on Pt. This experimental benchmark agrees with density functional theory (DFT) predictions made at the level of the generalized gradient approximation (GGA) for five different functionals, exhibiting a mean absolute error (MAE) of 25 meV. This is far better agreement than commonly expected for this level of theory. We speculate that this level of agreement may be a common feature for reactions that involve only species adsorbed on surfaces.
