1 · What the graph read from it

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.

2 · The registry

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

Hydrogen, as a clean and sustainable energy carrier, is currently predominantly produced by electrocatalytic water splitting, which relies on traditional precious-metal-based catalysts. The use of non-precious-metal-based catalysts to promote water splitting driven by renewable energy is gradually gaining favor. Recently, ferroelectric (FE) materials have attracted extensive attention in various catalytic reactions owing to their spontaneous polarization. As a model system with relatively simple reaction pathways, the hydrogen evolution reaction (HER) facilitates a deeper understanding of the role of polarization in catalytic mechanisms. This perspective highlights recent advances and conceptual developments in FE catalysts for the HER. First, we introduce the fundamental mechanisms of the HER and ferroelectricity. Second, based on structural design, FE catalysts are classified into single-phase FE catalysts, single-atom modified FE catalysts, FE heterostructure catalysts, and other engineered FE catalysts, and examples of research on each class of FE catalyst for the HER are discussed. Finally, prospects for the future development of FE catalysts for the HER are discussed from the perspectives of intrinsic FE metals, unconventional FE systems, and the coupling of spin with other physical properties. We hope this perspective will provide new insights and research references for exploring FE catalysts for the HER.
