Rational Design of Nickel-Based Heterostructured Electrocatalysts for Oxygen Evolution Reaction: Mechanisms, Advances, and Optimization Strategies.
Review in ChemSusChem, 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
As the most promising green hydrogen production technology to address the global energy crisis, electrolysis of water for hydrogen production requires highly active electrocatalysts. Building heterostructures is the most promising material design strategy to break through the limitations of oxygen evolution reaction (OER) kinetics and promote efficient hydrolysis. This review focuses on nickel-based heterostructured electrocatalysts, whose interface synergy between different components significantly improves catalytic performance. First, the three basic OER mechanisms were discussed, elucidating the relationship between micro interfaces and mechanisms. Then, the latest developments in different nickel-based material systems reveal how interfacial synergistic effects accelerate charge transfer and regulate intermediate adsorption. In addition, we focused on advanced performance optimization strategies, such as the latest advances in optimizing oxygen evolution performance through doping, defect control, and crystal phase engineering. Finally, we identified the challenges faced by this field in industrial applications and pointed out the integration of in situ characterization, theoretical calculations, and artificial intelligence design to achieve controllable preparation of interface active sites. This review provides important theoretical references for the design and development of a new generation of high-performance and scalable OER electrocatalysts, helping to promote the high-quality development of the green hydrogen energy industry.
