Nonprecious bifunctional electrocatalysts for oxygen electrode reactions.
Review in Beilstein journal of nanotechnology, 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 two most crucial reactions in energy storage and conversion systems are oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). However, their sluggish kinetics arise the need for commercially feasible bifunctional electrocatalysts to assist the reaction by improving its kinetics at the same time ensuring durability and also taking cost into account. The fundamentals of the oxygen electrodes are discussed followed by various techniques adopted by researchers to tune the electronic structures of carbon- and transition metal-based nanostructures towards enhanced activity in ORR/OER. Emphasis is placed on correlating catalyst structure/composition with electrocatalytic properties, simultaneously highlighting the persistent challenges. Hence, the review provides an overview on the recent advances in the field of non-precious bifunctional electrocatalysts for oxygen electrode reactions, which will serve as a foundation for their application in various fields including metal-air batteries.
